LMP90077 - Sensor AFE

General Description

The LLMP9007x and LMP90080 are highly integrated, multi-channel, low-power 16-bit Sensor AFEs.

The devices feature a precision, 16-bit Sigma Delta Analog-to-Digital Converter (ADC) with a lownoise programmable gain amplifier and a fully differential high impedance analog input multiplexer.

Key Features

  • 1 16-Bit Low-Power Sigma Delta ADC.
  • True Continuous Background Calibration at All Gains.
  • In-Place System Calibration Using Expected Value Programming.
  • Low-Noise Programmable Gain (1x - 128x).
  • Continuous Background Open/Short and Out of Range Sensor Diagnostics.
  • 8 Output Data Rates (ODR) with Single-Cycle Settling.
  • 2 Matched Excitation Current Sources from 100 µA to 1000 µA (LMP90080/LMP90078).
  • 4-DIFF / 7-SE Inputs (LMP90080/.
