产品说明

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 voltage. The programmability of the LMP91050 enables it to support multiple thermopile sensors with a single design as opposed to the multiple discrete solutions.

The LMP91050 features a programmable gain amplifier (PGA), dark phase offset cancellation, and an adjustable common-mode generator (1.15 V or 2.59 V) which increases output dynamic range. The PGA offers a low-gain range of 167 V/V to 1335 V/V plus a high-gain range of 1002 V/V to 7986 V/V which enables the user to use thermopiles with different sensitivities. The PGA is highlighted by low-gain drift (100 ppm/°C), output offset drift (1.2 mV/°C at G = 1002 V/V), phase delay drift (500 ns) and noise specifications (0.1 μVRMS 0.1 to 10Hz).
