Texas Instruments' LMP90100 is a highly integrated, multi-channel, low-power 24-bit sensor AFE. The device features a precision, 24-bit Sigma Delta Analog-to-Digital Converter (ADC) with a low-noise programmable gain amplifier and a fully differential high-impedance analog input multiplexer. A true continuous background calibration feature allows calibration at all gains and output data rates without interrupting the signal path. The background calibration feature essentially eliminates gain and offset errors across temperature and time, providing measurement accuracy without sacrificing speed and power consumption. The LMP90100 also features continuous background sensor diagnostics, allowing the detection of open and short circuit conditions and out-of-range signals without requiring user intervention, resulting in enhanced system reliability.
