Overview
1 Overview
The INA193 is a current-shunt monitor with voltage output. The INA193EVM consists of one PCB. The
EVM consists of the INA193 device, screw-terminals, and test points for external hardware connections.

2 Quick Start Setup and Use
Follow these steps to set up and use the INA193EVM:
1. Connect an external dc supply voltage (between 2.7 V and 18 V) to the V+ pin referenced to the GND
pin of the J1 terminal block.
2. Connect the desired input to the J2 terminal block. This desired input is either a external shunt resistor
or a differential voltage source with a common-mode voltage of –16 V to +80 V referenced to the GND
pin.

3 Hardware
The INA193EVM provides basic functional evaluation of the INA193. The fixture layout is not intended to
be a model for the target circuit, and is not laid out for electromagnetic compatibility (EMC) testing.
The layout of the INA193EVM PCB provides the following features:
• Ease of access to all device pins
• Multiple input signal options
• Optional surface-mount shunt
• Optional input filter
• Evaluate with and without a shunt resistor:
– The INA193EVM measures differential voltage both with and without a shunt resistor. Connect both
sides of an external shunt resistor to measure current, or omit the shunt resistor and apply a
differential voltage directly to the device input.
• INA19x family compatibility:
– INA193 can be desoldered and replaced with the INA194 or INA195 to evaluate other gains
available in this product family.
– INA196, INA197, and INA198 are the same devices in the same package, but with different pinouts.
The corresponding gains of the INA193 (20 V/V), INA194 (50 V/V), and INA195 (100 V/V) serve as
evaluation modules for those products as well.
Refer to the INA19x product data sheet for comprehensive information about this family of current-shunt
monitor devices.
