INA141  
Precision, Low Power, G = 10, 100  
INSTRUMENTATION AMPLIFIER  
FEATURES  
LOW OFFSET VOLTAGE: 50µV max  
LOW DRIFT: 0.5µV/°C max  
DESCRIPTION  
The INA141 is a low power, general purpose instru-  
mentation amplifier offering excellent accuracy. Its  
versatile 3-op amp design and small size make it ideal  
for a wide range of applications. Current-feedback  
input circuitry provides wide bandwidth even at high  
gain (200kHz at G = 100).  
ACCURATE GAIN: ±0.05% at G = 10  
LOW INPUT BIAS CURRENT: 5nA max  
HIGH CMR: 117dB min  
INPUTS PROTECTED TO ±40V  
WIDE SUPPLY RANGE: ±2.25 to ±18V  
LOW QUIESCENT CURRENT: 750µA  
8-PIN PLASTIC DIP, SO-8  
Simple pin connections set an accurate gain of 10 or  
100V/V without external resistors. Internal input pro-  
tection can withstand up to ±40V without damage.  
The INA141 is laser trimmed for very low offset  
voltage (50µV), drift (0.5µV/°C) and high common-  
mode rejection (117dB at G = 100). It operates with  
power supplies as low as ±2.25V, and quiescent  
current is only 750µA—ideal for battery operated  
systems.  
APPLICATIONS  
BRIDGE AMPLIFIER  
THERMOCOUPLE AMPLIFIER  
RTD SENSOR AMPLIFIER  
MEDICAL INSTRUMENTATION  
DATA ACQUISITION  
The INA141 is available in 8-pin plastic DIP, and  
SO-8 surface-mount packages, specified for the –40°C  
to +85°C temperature range.
