Product Overview

The LMP91051EVM evaluation kit is designed to ease evaluation and design in of LMP91051 configurable AFE for nondispersive infrared (NDIR). The LMP91051 is a dual channel programmable integrated sensor analog front end (AFE) data capturing and evaluations are simplified by connecting the SPIO-4 digital controller board (SPIO-4 board) to a PC via USB and running the sensor AFE software. The data capture board will generate the SPI signals to communicate to and capture data from the LMP91051. The user will also have the option to evaluate the LMP91051 without using the SPIO-4 board or the sensor AFE software. The onboard data converter will digitize the LMP91051's analog output and the software will display these results in time domain and histogram. The software also allows customers to write to and read from registers, to configure the device's gain, output offset and common mode voltage and most importantly to configure and learn about the LMP91051.
  • Dual channel input
  • Programmable gain amplifier
  • Dark signal offset cancellation
  • Supports external filtering
  • Common mode generator and 8bit DAC
