LMP90078MHE/NOPB

Analog Front End (AFE) Overview

The LMP90078MHE/NOPB is a multi-channel, low-power 16-bit Sensor Analog Front End (AFE) manufactured by Texas Instruments. It integrates four delta-sigma analog-to-digital converters with true continuous background calibration to maintain accuracy without external reference adjustments. The device supports both differential and single-ended input types via an SPI interface. It operates on analog supply voltages ranging from 2.85 V to 5.5 V and digital supply voltages from 2.7 V to 5.5 V. Packaged in an HTSSOP-28 format for surface mount installation, it provides a sampling rate of 214.6 S/s per channel.

Analog Front End (AFE) Feature Summary

• Four-channel 16-bit resolution with sigma-delta architecture
• True continuous background calibration system
• Supports differential and single-ended input configurations
• SPI serial interface for data communication

Analog Front End (AFE) Applications

• Multi-channel sensor signal conditioning
• Low-power data acquisition systems
• Industrial process monitoring
• Environmental sensing networks

Analog Front End (AFE) Selection Notes

Select this component when designing systems requiring simultaneous multi-channel acquisition with high precision. Verify that the application requires the specific 214.6 S/s sampling rate and 16-bit resolution. Ensure the power budget accommodates the specified analog and digital voltage ranges of up to 5.5 V.

Analog Front End (AFE) Part Context

This part belongs to the LMP9007x/LMP90080 Sensor AFE family from Texas Instruments. It is functionally related to the LMP90078MHE variant and shares specifications with other devices in the series designed for low-power, high-accuracy sensor applications.

Analog Front End (AFE) Replacement Considerations

The LMP90078MHE is a direct equivalent part number within the same product line. Other members of the LMP9007x/LMP90080 family may offer similar features but require verification of pin compatibility and specific channel counts.
