INA В® INA2141 214 INA 1 214 1 Dual, 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 INA2141 is a low power, dual 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 EXCELLENT GAIN ACCURACY:
В±0.05% max at G = 10
в—Џ LOW INPUT BIAS CURRENT: 5nA max
в—Џ HIGH CMR: 117dB min (G = 100)
в—Џ INPUTS PROTECTED TO В±40V 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 WIDE SUPPLY RANGE: В±2.25V to В±18V
в—Џ LOW QUIESCENT CURRENT: 750ВµA/IA The INA2141 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 ±2.25V, and quiescent current is only 750µA per amplifier—ideal for battery
operated systems. в—Џ 16-PIN PLASTIC DIP, SOL-16 APPLICATIONS
