40 μA Micropower Instrumentation Amplifier in WLCSP Package
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.
The AD8235 is an excellent choice for signal conditioning. Its low input bias current of 50 pA and high CMRR of 110 dB (G = 100) offer tremendous value for its size and low power.
It is specified over the extended industrial temperature range of −40°C to 125°C.

In-Amp Diamond Plot Tool
The Diamond Plot Tool is a web application that generates a configuration-specific Output Voltage Range vs. Input Common-Mode Voltage graph, also known as the Diamond Plot, for Analog Devices Instrumentation Amplifiers. Based on user inputs such as supply voltage, gain, and input signal range, the tool detects saturation and recommends in-amps for which the input signal is in-range and the configuration is valid. Avoid saturation, find the best in-amp for your design, and save time.
