AD8235 40 μA Micropower Instrumentation Amplifier in WLCSP Package
The AD8235 is the smallest and lowest power instrumentation
amplifier in the industry. It is available in a 1.5 mm × 2.2 mm
wafer level chip scale package (WLCSP). The AD8235 draws
a maximum quiescent current of 40 μA. In addition, it draws a
maximum 500 nA of current during shutdown mode, making
it an excellent instrumentation amplifier for battery powered,
portable applications.
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-torail
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.
