LMP91050 Description
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 plete signal path solution between a sensor and microcontroller that generates an output voltage proportional to the thermopile voltage. The programmability of the LMP91050 enables it to support multiple thermopile sensors with a single design as...
