LMP93601NHZT

Analog Front End (AFE) Overview

The LMP93601NHZT is a low-noise, high-gain analog front-end (AFE) designed for thermopile sensors. It integrates three differential EMI-protected channels with a precision 16-bit ADC. The device operates within a temperature range of -25°C to 85°C and utilizes a 24-WFQFN exposed pad package. Key specifications include a maximum height of 0.8 mm and support for sampling rates optimized for monitoring thermopile arrays up to 16x16.

Analog Front End (AFE) Feature Summary

Analog Front End (AFE) Procurement Notes

Verify the specific suffix NHZT against the manufacturer's official ordering guide to ensure correct packaging and tape-and-reel specifications. Confirm that the 24-WFQFN package dimensions align with your PCB footprint requirements. Cross-reference the operating temperature range of -25°C to 85°C with your system's environmental constraints before finalizing procurement.

Analog Front End (AFE) Selection Notes

Select this component when designing systems requiring high-resolution digitization of weak thermopile signals. The integrated EMI protection makes it suitable for electrically noisy environments. Ensure the application benefits from the three-channel architecture for multi-point sensing or redundancy without requiring external multiplexing circuitry.

Analog Front End (AFE) Part Context
