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.
