MAX41400 - Precision Instrumentation Amplifier

General Description

The MAX41400 is a low-power, high-precision instrumentation amplifier with programmable gain through input pins.

Available in a space-saving, 9-bump wafer-level package (WLP) with a 0.4mm bump pitch, it is designed for use in portable medical and industrial sensor applications.

Key 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 gainsetting resistors are located inside the device, thus minimizing gain drift variations over the temperature range. The MAX41400 features rail-to-rail CMOS inputs and outputs; a 28kHz, -3dB bandwidth at just 65µA (typ) supply current; and 25µV (max) zero-drift input offset voltage over time and temperature. The zero-drift feature eliminates the high 1/f noise typical.
