• Download Presentation

This presentation provides an overview of the LMP90100 Multi-Channel 24-bit Sensor AFE:

• Multi-channel Sensor AFE with a 24-bit Sigma Delta ADC core
• 4 differential or 7 single-ended flexible/programmable Mux routing inputs
• Continuous background sensor diagnostics reduce downtime and improve system efficiency
• Ideal for high-precision, multi-sensor temperature sensors, pressure sensors, and load cells
• Industrial process control, medical, and test & measurement applications

Part of the Sensor AFE family, the LMP90100 is a configurable IC that provides a complete integrated signal path solution between sensor and microcontroller for high-precision, multi-channel sensing applications. It features: Up to 21.5 effective bits; True continuous background calibration at all gains; Continuous background sensor diagnostics; Programmable data rates with single-cycle settling; Dual programmable 0.1% matched sensor excitation sources; A flexible, programmable mux, which easily accommodates 4 differential or 7 single-ended measurements or any combinations thereof.

Applications include temperature transmitters (RTD, thermistors, thermocouples), pressure, force, load and strain sensors.
