LMP90080MHE/NOPB

Analog Front End (AFE) Overview

The LMP90080MHE/NOPB is a 16-bit, 7-channel delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It operates with a sampling rate of 214.6 SPS and supports differential or single-ended inputs. The device features an integrated programmable gain amplifier (PGA) and excitation current sources (iDACs). It functions 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. The component utilizes an SPI interface and is housed in a 28-pin HTSSOP package. It supports operation within a temperature range of -40°C to +125°C.

Analog Front End (AFE) Feature Summary

• Integrates a 16-bit sigma-delta ADC with seven multiplexed channels for high-resolution signal acquisition.
• Includes built-in programmable gain amplifiers and excitation current sources to simplify sensor interfacing.
• Supports both differential and single-ended input configurations for versatile application compatibility.

Analog Front End (AFE) Applications

Analog Front End (AFE) Procurement Notes

Verify the specific suffix 'E' indicates the tape and reel packaging variant distinct from tube packages. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure voltage levels match the specified analog and digital supply ranges to prevent operational faults.

Analog Front End (AFE) Selection Notes

Select this component when multiple high-precision channels are required within a compact form factor. The integrated PGA and iDACs reduce external component count compared to discrete solutions. Consider the 214.6 SPS speed limit for applications not requiring high-frequency sampling.
