INA131

Precision G = 100

INSTRUMENTATION AMPLIFIER

DESCRIPTION

FEATURES

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.

● LOW OFFSET VOLTAGE: 50µV max

● LOW DRIFT: 0.25µV/°C max

● LOW INPUT BIAS CURRENT: 2nA max

● HIGH COMMON-MODE REJECTION:

On-chip laser trimmed resistors accurately set a fixed

gain of 100. The INA131 is laser trimmed to achieve

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

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

protection can withstand up to ±40V inputs without

damage.

110dB min

● INPUT OVERVOLTAGE PROTECTION:

±40V

● WIDE SUPPLY RANGE: ±2.25 to ±18V

● LOW QUIESCENT CURRENT: 3mA

● 8-PIN PLASTIC DIP

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

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

range.

APPLICATIONS

● BRIDGE AMPLIFIER

● THERMOCOUPLE AMPLIFIER

● RTD SENSOR AMPLIFIER

● MEDICAL INSTRUMENTATION
