LMP90097MHX/NOPB

Analog Front End (AFE) Overview

The LMP90097MHX/NOPB is a general-purpose analog front-end (AFE) featuring a single 24-bit delta-sigma analog-to-digital converter (ADC). It integrates four programmable gain amplifiers (PGAs) and supports SPI communication. The device operates on dual power supplies, with an analog range of 2.85 V to 5.5 V and a digital range of 2.7 V to 5.5 V. It delivers a sampling rate of 214.6 SPS and consumes 1.2 mW of power. Housed in a 28-pin HTSSOP package with an exposed pad, it functions within a temperature range of -40°C to +125°C.

Analog Front End (AFE) Feature Summary

• Integrated 24-bit delta-sigma ADC with 214.6 SPS sampling rate
• Four-channel input architecture with integrated programmable gain amplifiers (PGA)
• Low power consumption of 1.2 mW
• SPI interface for digital communication

Analog Front End (AFE) Applications

• Industrial process control systems requiring high-resolution signal conditioning
• Precision measurement instrumentation
• Medical equipment utilizing low-frequency sensor inputs

Analog Front End (AFE) Procurement Notes

Verify the specific suffix 'X' indicates tape-and-reel packaging rather than tube. Confirm RoHS compliance status through official manufacturer documentation. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Validate supply chain authenticity via authorized Texas Instruments distributors.

Analog Front End (AFE) Selection Notes

Select this component when four differential or eight single-ended channels are required with integrated amplification. Compare against the LMP90097MH/NOPB variant if tube packaging is preferred over reel. Ensure system voltage requirements align with the specified 2.7 V to 5.5 V digital supply range.

Analog Front End (AFE) Part Context

This part belongs to the LMP90097 family of analog front-ends designed for precision data acquisition. The MHX designation specifically denotes the surface-mount HTSSOP-28 package configuration supplied in a reel format, distinguishing it from the tube-packaged MH variant.
