LMP90078MH/NOPB

Analog Front End (AFE) Overview

The LMP90078MH/NOPB is a 16-bit, four-channel delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with an analog supply voltage range of 2.85 V to 5.5 V and a digital supply voltage range of 2.7 V to 5.5 V. The device supports a maximum sampling rate of 214.6 samples per second and features a serial peripheral interface (SPI). Packaged in a heat sink thin-shrink small-outline package (HTSSOP-28), it is designed for applications requiring high-resolution data acquisition with differential or single-ended input configurations.

Analog Front End (AFE) Feature Summary

• 16-bit resolution with four independent channels
• Delta-sigma architecture supporting up to 214.6 S/s sampling rate
• Dual power supply operation: 2.85–5.5 V analog, 2.7–5.5 V digital
• SPI-compatible serial interface for data transfer

Analog Front End (AFE) Applications

• Industrial process control systems
• Medical instrumentation data acquisition
• High-resolution sensor interfaces

Analog Front End (AFE) Selection Notes

Select the LMP90078MH/NOPB when four-channel 16-bit resolution is required at low sampling rates. Verify that the system power supplies align with the specified analog (2.85–5.5 V) and digital (2.7–5.5 V) ranges. Ensure the PCB layout accommodates the HTSSOP-28 package and provides adequate thermal dissipation for the exposed pad.

Analog Front End (AFE) Part Context

This component belongs to the LMP90078 family of precision ADCs from Texas Instruments. It shares architectural similarities with other devices in the series but is distinguished by its specific 16-bit resolution and four-channel configuration. The NOPB suffix indicates lead-free construction compliant with RoHS standards.
