GENERAL DESCRIPTION
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.
