LMP90100MHX/NOPB

Analog Front End (AFE) Overview

The LMP90100MHX/NOPB is a multi-channel, low-power 24-bit Sensor Analog Front End (AFE) from Texas Instruments. It integrates true continuous background calibration to eliminate gain and offset errors across all gains and output data rates. The device features an SPI interface for communication and is housed in a surface-mount package. Designed for high-precision applications, it supports multiple channels with sigma-delta architecture, ensuring accurate sensor signal conditioning without external calibration components.
