The LMP90100EB/NOPB is designed to ease evaluation and design in LMP90100 24bit fully programmable low power ΣΔ ADC with true continuous background calibration. Data capturing and static evaluations are simplified by connecting the SPIO4 digital controller board (SPIO4 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 LMP90100. The user will also have the option to evaluate the LMP90100 without using the SPIO4 board or the Sensor AFE software. The LMP90100 will digitize the analog input 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 calibrate the device or the system"s gain, offset and scale settings and most importantly, to configure and learn about the LMP90100.
