LMP91050 Datasheet (Texas Instruments)

LMP91050, Configurable AFE

The LMP91050 device is a 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 vo
