Analog Devices AD8235 Instrumentation Amplifier Datasheet
The AD8235 is a 40 pA micropower instrumentation amplifier offered in an 11‑ball wafer‑level chip‑scale package (WLCSP). It operates from 1.8 V to 5.5 V and draws as little as 30 µA quiescent current, making it suitable for portable and battery‑powered medical and low‑side current‑sense applications.
Key features include a low input bias current of 50 pA, a typical CMRR of 110 dB at gain 100, rail‑to‑rail input and output, and a shutdown pin that reduces current to 500 nA. The device supports gain settings from 5 to 200 via a single external resistor and provides a short‑circuit limit of 55 mA.
