Analog Devices / Maxim Integrated MAX41400 Instrumentation Amplifiers
Analog Devices MAX41400 Instrumentation Amplifiers are low-power, high-precision instrumentation amplifiers with programmable gain through input pins. The MAX41400 are housed in a space-saving, 9-bump wafer-level package (WLP) with a 0.4mm bump pitch. It's ideal for portable medical and industrial sensor applications. The device features internal EMI filters to protect from RF disturbances and EMI. The internal fixed gain can be selected from 10V/V to 250V/V. The gain-setting resistors are both inside the Analog Devices MAX41400 Instrumentation Amplifiers, thus minimizing gain drift variations over the temperature range.Features
