ADI's AD8235 is one of the industry's smallest and lowest power instrumentation amplifiers. The AD8235 measures 1.5 mm x 2.2 mm with a wafer level chip scale package (WLCSP) and draws a maximum quiescent current of 40 µA. Additionally, it draws only 6 nA (typical) of current during shutdown mode. The AD8235's miniscule size, combined with its ultra-low power consumption, makes it an excellent instrumentation amplifier for battery-powered and portable medical devices and consumer-health products.
The AD8235 can operate on supply voltages as low as 1.8 V. The input stage allows for wide rail-to-rail input voltage range without the crossover distortion common in other designs. The rail-to-rail output enables easy interfacing to ADCs.
