LMP90078MHX/NOPB

Analog Front End (AFE) Overview

The LMP90078MHX/NOPB is a 16-bit, four-channel delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It supports sampling rates up to 214.6 samples per second and accepts both differential and single-ended input signals. The device operates with an analog supply voltage ranging from 2.85 V to 5.5 V and a digital supply voltage between 2.7 V and 5.5 V. Communication is handled via an SPI interface. The component is housed in a 28-pin HTSSOP package and functions within a temperature range of -40°C to +125°C.

Analog Front End (AFE) Feature Summary

• 16-bit resolution with four independent channels
• Delta-sigma architecture supporting up to 214.6 SPS
• Flexible input configuration for differential or single-ended signals
• SPI digital interface for data transfer

Analog Front End (AFE) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Precision measurement instrumentation
• Data acquisition systems with moderate speed requirements

Analog Front End (AFE) Selection Notes

Select this component when a multi-channel, high-resolution ADC is required for low-speed applications. Verify that the system power supplies align with the specified analog (2.85 V–5.5 V) and digital (2.7 V–5.5 V) ranges. Ensure the PCB layout accommodates the 28-lead HTSSOP package and that the host microcontroller supports the necessary SPI protocol.

Analog Front End (AFE) Part Context

This part belongs to the LMP90078 series of precision ADCs from Texas Instruments. It is categorized under Data Converter ICs within the PMIC segment. The device is designed for applications needing multiple inputs with high accuracy but without the need for high-speed sampling, distinguishing it from faster SAR or pipeline ADC families.
