Sensor AFE System: Multi-Channel, Low-Power 16-Bit Sensor AFE with True Continuous Background Calibration
1.0 General Description
The LMP90080/LMP90079/LMP90078/LMP90077 are highly integrated, multi-channel, low-power 16-bit Sensor AFEs. The devices feature a precision, 16-bit Sigma Delta Analogto-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.
