LMP90100MH/NOPB

Analog Front End (AFE) Overview

The LMP90100MH/NOPB is a multi-channel, low-power 24-bit Sensor Analog Front End (AFE) from Texas Instruments. It integrates four delta-sigma analog-to-digital converters with programmable gain amplifiers and excitation sources. The device employs true continuous background calibration to eliminate gain and offset errors across all gains and output data rates. It features an SPI interface for communication and operates within a specified temperature range. This component is designed for high-precision sensor applications requiring minimal signal conditioning overhead.

Analog Front End (AFE) Feature Summary

• True continuous background calibration eliminates gain and offset errors over time and temperature
• Integrates four 24-bit delta-sigma ADCs with programmable gain amplifiers
• Includes integrated excitation sources for bridge sensors
• SPI digital interface for system connectivity

Analog Front End (AFE) Applications

• Industrial process control systems
• High-precision weighing scales
• Medical instrumentation
• Strain gauge and pressure sensor interfaces

Analog Front End (AFE) Part Context

The LMP90100MH/NOPB belongs to the LMP90100 family of Sensor AFEs. It shares core functionality with variants such as the LMP90100MHE/NOPB and related models like the LMP90097, differing primarily in package type and specific pinout configurations. The 'MH' suffix indicates a specific surface-mount package option within this product line.

Analog Front End (AFE) Replacement Considerations

Direct replacements include the LMP90100MHE/NOPB, which offers identical electrical performance but utilizes an MHE package instead of MH. Designers must verify mechanical footprint compatibility when substituting between these package variants.
