LMP90079MH/NOPB

Analog Front End (AFE) Overview

The LMP90079MH/NOPB is a 16-bit, 7-channel delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It features an integrated programmable gain amplifier (PGA) and operates with single-ended inputs. The device supports SPI digital interfaces and achieves sampling rates up to 214.6 samples per second. Power consumption is specified at 1.2 mW. Analog supply voltage ranges from 2.85 V to 5.5 V, while the digital supply operates between 2.7 V and 5.5 V. 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 7 independent input channels
• Integrated Programmable Gain Amplifier (PGA)
• Sigma-Delta architecture with SPI interface
• Low power consumption of 1.2 mW

Analog Front End (AFE) Applications

• Industrial process control systems
• Multi-channel sensor data acquisition
• Precision measurement instrumentation

Analog Front End (AFE) Procurement Notes

Verify the specific suffix 'MH' against the manufacturer's datasheet to confirm package type and tape/reel specifications. Ensure compatibility with system voltage levels, as analog and digital supplies have distinct minimum thresholds. Confirm humidity sensitivity handling requirements during storage and assembly processes.

Analog Front End (AFE) Selection Notes

Select this component for applications requiring multiple single-ended inputs with high resolution. The integrated PGA reduces external component count compared to discrete solutions. Verify that the required sampling rate does not exceed 214.6 SPS and that the input signal range aligns with the PGA capabilities and reference voltage limits.

Analog Front End (AFE) Part Context

This part belongs to the LMP90079 series of multi-channel ADCs. It shares architectural similarities with other devices in the family but is distinguished by its specific channel count and pinout configuration. The 'NOPB' suffix indicates lead-free construction compliant with RoHS standards.

Analog Front End (AFE) Replacement Considerations

Direct substitutes within the same family include the LMP90079MHE/NOPB, which differs primarily in packaging format. Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
