В® INA141 INA 141 INA 141 Precision, Low Power, G = 10, 100
INSTRUMENTATION AMPLIFIER
FEATURES DESCRIPTION в—Џ LOW OFFSET VOLTAGE: 50ВµV max
в—Џ LOW DRIFT: 0.5ВµV/В°C max The INA141 is a low power, general purpose instrumentation 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). в—Џ ACCURATE GAIN: В±0.05% at G = 10
в—Џ LOW INPUT BIAS CURRENT: 5nA max
в—Џ HIGH CMR: 117dB min
в—Џ INPUTS PROTECTED TO В±40V
в—Џ WIDE SUPPLY RANGE: В±2.25 to В±18V Simple pin connections set an accurate gain of 10 or
100V/V without external resistors. Internal input protection can withstand up to В±40V without damage. в—Џ LOW QUIESCENT CURRENT: 750ВµA
в—Џ 8-PIN PLASTIC DIP, SO-8 в—Џ BRIDGE AMPLIFIER The INA141 is laser trimmed for very low offset
voltage (50ВµV), drift (0.5ВµV/В°C) and high commonmode rejection (117dB at G = 100). It operates with
power supplies as low as В±2.25V, and quiescent
current is only 750µA—ideal for battery operated
systems. в—Џ THERMOCOUPLE AMPLIFIER
в—Џ RTD SENSOR AMPLIFIER
в—Џ MEDICAL INSTRUMENTATION The INA141 is available in 8-pin plastic DIP, and
SO-8 surface-mount packages, specified for the –40°C
to +85В°C temperature range. APPLICATIONS в—Џ DATA ACQUISITION
