DESCRIPTION

The INA131 is a low cost, general purpose G = 100

instrumentation amplifier offering excellent accuracy.

Its 3-op amp design and small size make it ideal for

a wide range of applications.

On-chip laser trimmed resistors accurately set a fixed

gain of 100. The INA131 is laser trimmed to achieve

very low offset voltage (50mV max), drift (0.25mV/°C

max), and high CMR (110dB min). Internal input

protection can withstand up to ±40V inputs without

damage.

The INA131 is available in a 8-pin plastic DIP. They

are specified over the –40°C to +85°C temperature

range.
