1 Overview

The INA190 devices are voltage output, high- and low-side measurement, bi-directional, zero-drift current shunt monitors. This family of devices has gains that range from 25 V/V to 500 V/V. The voltage developed across the device inputs is amplified by the corresponding gain of the specific device and is presented at the output pin. These devices can accurately sense voltage drops across shunts at common­mode voltages from –0.1 V to 40 V, independent of supply voltages. These devices operate with supply voltages between 2.7 V and 5.5 V and draw a maximum of 65 µA at room temperature. The low offset of the zero-drift architecture enables the sensing of very small differential input voltage which helps widen the usable input dynamic range. Additionally, the INA190 has a very low input bias current and thus, can easily measure microamps of current.
The INA190 devices are currently available in a QFN package. Table 1 summarizes the available device gain options.

Overview

2 INA190EVM Hardware

The INA190EVM is intended to provide basic functional evaluation of the INA190 device family. The fixture layout is not intended to be a model for the target circuit, nor is it laid out for electromagnetic compatibility (EMC) testing. The INA190EVM consists of one PCB with an option to cut out six individual PCBs, one for each of the five gain variants (INA190A1, INA190A2, INA190A3, INA190A4, and INA190A5). Each of the PCB cutouts consists of one INA190AXIRSW device (where x is 1, 2, 3, 4, and 5) and test points for external hardware connections, as well as pads to solder down optional circuitry. A sixth board includes a guarding scheme to guard the input traces thus, preventing leakage current. This board has the INA190A5 as the installed test device.

2.1 Features

The INA190EVM PCB provides the following features:
Evaluation of all gain options through provided device boards
Ease of access to device pins with test points
Pads for optional filtering at the input pins, output pin, and reference pin
Pads for optional reference buffer driving circuit with SOT-23-5 op amp
Multiple input signal options including a method to solder the shunt resistor and safely measure current up to 15 A

Quick Start Setup and Use

3 Quick Start Setup and Use

Follow these procedures to set up and use one of the panels of the INA190EVM. For the following instructions, x = 1, 2, 3, 4, 5, or [blank].
Step 1. Choose the desired gain option panel. Step 2. Ensure the J3x and J4x headers for the enable (EN) and reference (VREF) pins are set to
the appropriate voltages. For the device to amplify the input signal, it must be enabled by connecting the VS and ENABLE pins of J4x. For the device to have a ground reference, the REF and GND pins for J3x must be connected. If a custom reference voltage is desired, remove the jumper from J3x and drive the REF pin with an external voltage source.
Step 3. Connect an external DC supply voltage between 1.7 V and 5.5 V to a VS test point (TP1x or
TP3x), and connect the ground reference of that supply to a GND test point (TP2x,TP4x, TP8x) on same panel.
Step 4. Provide an input voltage signal (referenced to GND) to the IN+ and IN– pins by connecting
signal leads to J0x and J1x quick-fit tabs. This is explained in Section 3.1.

3.1 Measurements

The INA190EVM allows the user to either simulate the voltage developed across a sense resistor based on a given set of system conditions, or to connect it remotely to an existing shunt already included in an example application. Additionally, a surface-mount technology (SMT) shunt resistor can be soldered across the IN+ and IN– pads these inputs can be connected in-series with their system and load.
To configure a measurement evaluation without a shunt resistor, follow these procedures:
1. Connect a differential voltage to the IN+ (J0x) and IN– (J1x) tabs. With the reference voltage set at ground, ensure that the IN+ pin is the more positive of the two inputs.
2. Additionally, if the differential voltage supply is a floating supply, connect a –0.1-V to 40-V common­mode voltage to the inputs by connecting the positive lead of the external voltage source to the IN– (J1x) tab and source ground to a GND testpoint. This effectively raises the absolute voltage of the input pins, while still retaining a positive input differential signal.
3. Measure the output voltage at the OUT test point (TP5x).
To configure a measurement evaluation with a shunt resistor, follow these procedures:
1. Solder down a resistor at the R8x pad that connects the IN+ (J0x) and IN– (J1x) inputs.
2. Connect the IN+ (J0x) and IN– (J1x) tabs in series with the load and bus voltage sources while powered off.

WARNING
If measuring current, please first ensure the equipment (shunt resistor, wires, connectors, and so forth) being used can support the amperage and power dissipation. Secondly, ensure the current flowing through J0x and J1x does not exceed 15 A. If using the "Guarded Inputs" panel, ensure current flowing between J0 and J1 does not exceed 10 A. Failure to do any of this could result in hot surfaces (> 55°C), damage to the EVM, or personal injury.
3. Power on the system and measure the output voltage at the OUT test point (TP5x).
NOTE: The output voltage (if measured with respect to reference voltage) is equal to the gain of the
device multiplied by the differential voltage measured directly at the device input pins.

4 INA190EVM Circuit and Components

This section summarizes the INA190EVM components. For the following instructions, x = 1 to 5 or a [blank].

4.1 R5x, R6x, R7x, R3x,C2x, C3x, C4x, C9x

R5x, R6x, R7x, and R3x are factory-installed 0-resistors. C2x, C3x, C4x, and C9x are not populated except for C9x. Collectively, these pads allow for user-defined filters for the input, reference signal, and output. If a filter is desired, remove these resistors and replace them with > 0-SMT resistors and populate the capacitor pads with capacitors. Additional information regarding the use of input filtering is provided in INA190 Low Supply, Voltage Output, Low- or High-Side Measurement, Bidirectional, Zero-Drift
Series, Current-Shunt Monitors.

4.2 C1x, C5x

C1x and C5x are 0.1-µF power supply bypass capacitors.

4.3 R1x, R2x

R1x and R2x are resistors used to divide down VS supply voltage and drive a custom, on-board reference voltage into U2x if R2x and U2x are populated.

4.4 R4

R4 is a connection resistor for the "Guarded Inputs" panel. Populate this with a 0-resistor to connect the guarding plane to automatically be driven to the same voltage as the input common-mode voltage. This may only be necessary if measuring very small currents at high common-mode voltages.
INA190EVM Circuit and Components

4.5 R8x

R8x is unpopulated, but allows a surface-mount shunt resistor to be soldered down in between the IN+ and IN– inputs. If used, ensure R8x has proper power dissipation for the user-set current load. This resistor chosen must at a minimum have a 0603 Imperial footprint.

4.6 U1x - INA190

U1x is the location for the INA190x test device. Six device boards are supplied with the INA190EVM board. Each board is populated with one of the available device gains. This option allows users to test the devices and determine the gain setting that is best suited for a given application.
The following list of factors are involved in selecting the appropriate device:
The INA190 devices are identical with the exception of different gain settings.
The differential input voltage is either applied across the inputs or developed based on the load current that flows through the shunt resistor.
The limiting factor that requires attention to be given to device selection is the output voltage not exceeding the supply voltage or going below GND.
The selected device must allow the output voltage to remain within the acceptable range after the developed input voltage is amplified by the respective device gain. The output voltage must remain with the swing limitations specified for the device for response in the linear range.
An output below the minimum allowable output requires the selection of a device with a higher gain. Likewise, an output above the maximum allowable output requires the selection of a device with a lower gain.

4.7 U2x

U2x is not populated, but allows a SOT-23-5 operational amplifier to be soldered to the EVM. In conjunction with populating R1x and R2x with the desired ratio of resistances, U2x provides a low­impedance voltage source for the REF pin of the INA190. Two options to populate this pad are TLV6001IDBVR and TLV379IDBV.

INA190EVM Circuit and Components

4.8 J0x, J1x

J0x and J1x are 0.240 inch non-insulated, quick-fit terminals that are designed to insert into similarly-sized female receptacles. The kit provides two receptacles. Using insulated receptacles with J0x and J1x terminals allows the user to ensure a strong and safe connection between the current source and EVM when dealing with high currents.
If using the EVM to measure currents, ensure a proper power resistor is soldered at the R8x pad and the receptacles (connecting to J0x and J1x) and their crimped wires can support the amperage of the current being measured and the necessary power dissipation. Do not exceed 15 A of current flowing between J0x and J1x. If using the "Guarded Inputs" panel, ensure current flowing from J0 to J1 does not exceed 10 A. Failure to do any of this could result in hot surfaces (> 55°C), damage to the EVM, or personal injury.
Standard metal clips can electrically interface with these tabs for lower currents. The IN+ (J0x) and IN– (J1x) inputs accept a differential voltage that is amplified by the selected device
gain and is presented at the OUT test point (TP5x). These inputs could also be used to connect the differential voltage developed across an external shunt in an existing circuit. The acceptable differential input voltage range and polarity are determined by the supply voltage, reference voltage, and gain of the selected device.

WARNING

5 Reference Voltage Setup

The INA190 devices allow for the use of an external reference through the REF pin. The INA190EVM provides a test point to drive the REF pin externally or pads to solder a buffer amplifier to drive a custom voltage generated from the resistor divider off the VS power plane. The reference determines what offset the output will have and allows these devices to be used in both unidirectional and bi-directional current sensing applications.

5.1 Unidirectional Mode

Unidirectional refers to a load current that flows in only one direction. For unidirectional applications, the reference voltage can be set to ground or to 5 V. If the reference is set to ground, the output is set at near ground with no input voltage, and responds to input voltages that are positive with respect to IN– / Load. If the reference is set to 5 V, the output is set near 5 V with no input voltage, and responds to input voltages that are negative with respect to IN– / Load.

5.2 Bi-Directional Mode

Bi-directional refers to a load current that flows in both directions. For bi-directional applications, the reference voltage should be set anywhere within the GND to VS range. The voltage applied to the reference pin establishes the output voltage of the device with no input voltage. The output voltage is limited by the supply voltage minus the specified output swing to VS in the data sheet.

5.3 REF Pin Configuration

The REF test point (TP6x) allows configuration of the INA190EVM for either unidirectional or bi-directional operation. The INA190EVM has an onboard circuit that allows the supply of a custom reference voltage that is powered through the supply voltage.

Guarding Voltage - Using the "Guarded Inputs" Panel
5.3.1 U2x Buffer Not Populated
Jump pins 2 (REF) and 3 (GND) of the J3x header to make REF = GND. The jumper can be removed from the EVM and the REF test points (TP6x or pin 2 of J3x) can be driven with the external voltage source. Note this external source needs a common ground with the INA190 power source.
5.3.2 U2x Buffer Populated
Be sure to populate R2x. If R2x equals R1x, then the U2x buffer output will equal VS/2. Jump pins 2 (REF) and 1 (VS/2) of the J3x header to drive the REF pin with the output of U2x.

6 Guarding Voltage - Using the "Guarded Inputs" Panel

One panel on the INA190EVM is labeled as "Guarded Inputs" because it includes extra circuitry to help guard the input traces going into the IN+ and IN– pins of the INA190. When measuring a small current, it is desirable to minimize the input bias currents of the device, which is in the nanoamps. The input bias current could increase due to leakage currents sinking into a nearby ground plane and this is simply due to finite resistance of PCB material and a voltage potential. This voltage potential only grows as common­mode voltage increases. Guard the input traces with an isolated guarding plane and fence that is at the same potential and any leakage currents from the input traces will be significantly reduced. This technique is really more practical when dealing with currents in the picoamps level, but it is included to help evaluate any extreme cases: low-current or high common-mode voltage or both.
The guarding plane can be driven by an external voltage source using the VG tespoint (TP7) or by populating R4 with a 0-resistor, which will automatically tie common-mode voltage at the inputs to the guarding plane. If using the VG tespoint, ensure the external source has a common ground with the INA190.
