DESCRIPTION

The INA117 is a precision unity-gain difference
amplifier with very high common-mode input voltage
range. It is a single monolithic IC consisting of a
precision op amp and integrated thin-film resistor
network. It can accurately measure small differential
voltages in the presence of common-mode signals up
to ±200V. The INA117 inputs are protected from
momentary common-mode or differential overloads
up to ±500V.

In many applications, where galvanic isolation is not
essential, the INA117 can replace isolation amplifiers.
This can eliminate costly isolated input-side power
supplies and their associated ripple, noise and quies­cent current. The INA117’s 0.001% nonlinearity and
200kHz bandwidth are superior to those of conven­tional isolation amplifiers.

The INA117 is available in 8-pin plastic mini-DIP and
SO-8 surface-mount packages, specified for the –40°C
to +85°C temperature range. The metal TO-99 models
are available specified for the –40°C to +85°C and
–55°C to +125°C temperature range.

DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Texas Instru­ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.

ESD damage can range from subtle performance degrada­tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.

APPLICATION INFORMATION

Figure 1 shows the basic connections required for operation.
Applications with noisy or high-impedance power-supply lines

may require decoupling capacitors close to the device pins.
The output voltage is equal to the differential input volt-

age between pins 2 and 3. The common mode input
voltage is rejected.

Internal circuitry connected to the compensation pin 8 can­cels the parasitic distributed capacitance between the feed­back resistor, R2, and the IC substrate. For specified dy­namic performance, pin 8 should be grounded or connected
through a 0.1µF capacitor to an AC ground such as V+.

COMMON-MODE REJECTION

Common-mode rejection (CMR) of the INA117 is depend­ent on the input resistor network, which is laser-trimmed for
accurate ratio matching. To maintain high CMR, it is impor­tant to have low source impedances driving the two inputs.
A 75Ω resistance in series with pin 2 or 3 will decrease CMR
from 86dB to 72dB.

Resistance in series with the reference pins will also degrade
CMR. A 4Ω resistance in series with pin 1 or 5 will decrease
CMRR from 86dB to 72dB.

Most applications do not require trimming. Figures 2 and 3
show optional circuits that may be used for trimming offset
voltage and common-mode rejection.

TRANSFER FUNCTION

Most applications use the INA117 as a simple unity-gain
difference amplifier. The transfer function is:

VO = V3 – V

MEASURING CURRENT

The INA117 can be used to measure a current by sensing the
voltage drop across a series resistor, R

. Figure 4 shows the

S

INA117 used to measure the supply currents of a device
under test. The circuit in Figure 5 measures the output
current of a power supply. If the power supply has a sense
connection, it can be connected to the output side of RS to
eliminate the voltage-drop error. Another common applica­tion is current-to-voltage conversion, as shown in Figure 6.

matching of the INA117, degrading its CMR. Also, the input
impedance of the INA117 loads RS, causing gain error in the
voltage-to-current conversion. Both of these errors can be
easily corrected.

The CMR error can be corrected with the addition of a
compensation resistor, RC, equal in value to RS as shown in
Figures 4, 5, and 6. If RS is less than 20Ω, the degradation
in CMR is negligible and RC can be omitted. If RS is larger
than approximately 2kΩ, trimming RC may be required to
achieve greater than 86dB CMR. This is because the actual
INA117 input impedances have 1% typical mismatch.

If RS is more than approximately 100Ω, the gain error will
be greater than the 0.02% specification of the INA117. This
gain error can be corrected by slightly increasing the value
of RS. The corrected value, RS', can be calculated by:

Rk

•Ω

R

S

'–=

S

kR

Ω

S

Example: For a 1V/mA transfer function, the nominal,
uncorrected value for RS would be 1kΩ. A slightly larger
value, RS' = 1002.6Ω, compensates for the gain error due to
loading.

The 380kΩ term in the equation for RS' has a tolerance of
±25%, so sense resistors above approximately 400Ω may
require trimming to achieve gain accuracy better than 0.02%.

Of course, if a buffer amplifier is added as shown in Figure
7, both inputs see a low source impedance, and the sense
resistor is not loaded. As a result, there is no gain error or
CMR degradation. The buffer amplifier can operate as a
unity gain buffer or as an amplifier with non-inverting gain.
Gain added ahead of the INA117 improves both CMR and
signal-to-noise. Added gain also allows a lower voltage drop
across the sense resistor. The OPA1013 is a good choice for
the buffer amplifier since both its input and output can swing
close to its negative power supply.

Figure 8 shows very high input impedance buffer used to
measure low leakage currents. Here, the buffer op amp is
powered with an isolated, split-voltage power supply. Using
an isolated power supply allows full ±200V common-mode
input range.

NOISE PERFORMANCE

The noise performance of the INA117 is dominated by the
internal resistor network. The thermal or Johnson noise of

±200V max

these resistors produces approximately 550nV/√Hz noise.
The internal op amp contributes virtually no excess noise at
frequencies above 100Hz.

Many applications may be satisfied with less than the full
200kHz bandwidth of the INA117. In these cases, the noise
can be reduced with a low-pass filter on the output. The two­pole filter shown in Figure 9 limits bandwidth to 1kHz and
reduces noise by more than 15:1. Since the INA117 has a
1/f noise corner frequency of approximately 100Hz, a cutoff
frequency below 100Hz will not further reduce noise.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check

http://www.ti.com/productcontent for the latest availability information and additional product content details.

TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements

for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
