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.

NOTES: (1) Connected as difference amplifier (see Figure 1). (2) Nonlinearity is the maximum peak deviation from the best-fit straight line as a percent of full-scale
peak-to-peak output. (3) With zero source impedance (see discussion of common-mode rejection in Application Information section). (4) Includes effects of amplifier’s
input bias and offset currents. (5) Includes effects of amplifier’s input current noise and thermal noise contribution of resistor network.

PACKAGE/ORDERING INFORMATION
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
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.
