The AD8237 micro-power, zero-drift precision instrumentation amplifier is claimed to offer a power-efficient solution for precision signal and sensor conditioning, it features a low input offset drift of less than 0.3 µV/°C and an input signal range that extends 300 mV beyond the supply rails.
The AD8237 operates off a single supply voltage of 1.8 V to 5.5 V and is in a compact MSOP-8 package. The gain (1 to 1000) is set by the ratio of two external resistors, which combined with industry leading gain error performance, provides superior gain accuracy over temperature.
