LMP91051 Datasheet Configurable Afe

Manufacturer: Texas Instruments

Overview: LMP91051 www.ti.com SNAS581B – MARCH 2012 – REVISED MAY 2013 LMP91051 Configurable AFE for Nondispersive Infrared (NDIR) Sensing Applications Check for Samples:.

General Description

The LMP91051 is a dual channel programmable integrated Sensor Analog Front End (AFE) optimized for thermopile sensors, as typically used in NDIR applications.

It provides a complete signal path solution between a sensor and microcontroller that generates an output voltage proportional to the thermopile voltage.

The LMP91051’s programmability enables it to support multiple thermopile sensors with a single design as opposed to the multiple discrete solutions.
