GENERAL DESCRIPTION
●The AD8237 is a micropower, zero drift, rail-to-rail input and output instrumentation amplifier. The relative match of two resistors sets any gain from 1 to 1000. The AD8237 has excellent gain accuracy performance that can be preserved at any gain with two ratio-matched resistors.
●FEATURES
●Gain set with 2 external resistors
● Can achieve low gain drift at all gains
●Ideal for battery powered instruments
● Supply current: 115 µA
● Rail-to-rail input and output
● Zero input crossover distortion
●Designed for excellent dc performance
● Minimum CMRR: 106 dB
● Maximum offset voltage drift: 0.3 µV/°C
● Maximum gain error: 0.005% (all gains)
● Maximum gain drift: 0.5 ppm/°C (all gains)
● Input bias current: 1 nA guaranteed to 125°C
