LMP90100MHE/NOPB Datasheet PDF - TI

●The LMP90100MHE/NOPB is a Sensor AFE System features a highly integrated multichannel low-power 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. Another feature of the LMP90100 is continuous background sensor diagnostics, allowing the detection of open and short-circuits conditions and out-of-range signals, without requiring user intervention, resulting in enhanced system reliability. Two sets of independent external reference voltage pins allow multiple ratiometric measurements.
