LMP91000SDX/NOPB TI Sensor AFE | 14-WSON (4X4) | Configurable, Low Noise

Product Overview

The LMP91000SDX/NOPB is a configurable analog front-end (AFE) for electrochemical sensors, designed by Texas Instruments. It integrates a low-noise potentiostat, transimpedance amplifier, and programmable gain stages, enabling precise current-to-voltage conversion for gas detection, biosensing, and chemical analysis. Housed in a compact 14-WSON (4x4 mm) package, it operates from a single 2.7V to 5.5V supply, consuming only 10 µA typical quiescent current. The device supports three-electrode amperometric sensors and offers digital control via I2C interface for gain, bias voltage, and temperature compensation.
