Overview

The MAX41400ATB is a low-power, high-precision instrumentation amplifier that can be programmed with gain via input pins. The MAX41400ATB comes in a space-saving 10-pin TDFN package and is designed for portable medical and industrial sensor applications. The MAX41400ATB has an internal EMI filter that protects against RF interference and EMI. Internal fixed gain options range from 10V/V to 250V/V. The gain setting resistance is located inside the device, thereby sufficiently reducing gain drift variations over the temperature range.

The MAX41400ATB has rail-to-rail CMOS input and output; The -3dB bandwidth is 28kHz, and the supply current is only 65µA (typical value); Zero drift input offset voltage with time and temperature is 25µV (maximum). The zero-drift feature eliminates the high 1/f noise commonly found in CMOS input amplifiers, making the MAX41400ATB suitable for a variety of low-frequency measurement applications.
