LMP90079MHX/NOPB

Analog Front End (AFE) Overview

The LMP90079MHX/NOPB is a 16-bit, seven-channel delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It features an integrated programmable gain amplifier (PGA) and operates on a single supply voltage ranging from 2.85 V to 5.5 V for the analog section and 2.7 V to 5.5 V for the digital section. The device supports SPI communication and delivers a sampling rate of up to 214.6 samples per second. Designed for surface-mount applications, it utilizes an HTSSOP-28 package and functions within a temperature range of -40°C to +125°C, consuming 1.2 mW of power.

Analog Front End (AFE) Feature Summary

Analog Front End (AFE) Procurement Notes

Verify the specific suffix 'MHX' against the official datasheet to confirm the tape-and-reel packaging configuration. Ensure the ordering part number matches the exact pinout and electrical specifications required for the design. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and any recent lifecycle changes.

Analog Front End (AFE) Selection Notes

Select this component when multi-channel, high-resolution conversion is required in a compact form factor. The integrated PGA reduces external component count for low-level sensor signals. Verify that the system clock requirements align with the desired output data rate and that the SPI interface timing meets the microcontroller or DSP capabilities.

Analog Front End (AFE) Part Context

This part belongs to the LMP90079 family of precision ADCs. The 'MHX' suffix typically denotes the HTSSOP-28 package variant supplied in tape-and-reel format for automated assembly. It serves as a direct replacement for previous versions like the LMP90079MHE/NOPB, maintaining identical electrical performance while adapting to different packaging logistics.

Analog Front End (AFE) Replacement Considerations

The LMP90079MHE/NOPB is a confirmed equivalent part number offering identical functionality in a different package style. Verify pin compatibility if transitioning between HTSSOP variants. No other cross-model substitutes are documented in the provided source material.
