LMP90079MHE/NOPB

Analog Front End (AFE) Overview

The LMP90079MHE/NOPB is a seven-channel, 16-bit delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It integrates a programmable gain amplifier (PGA) and operates with single-ended inputs. The device supports an SPI interface and achieves a sampling rate of up to 214.6 samples per second. Power requirements include an analog supply range of 2.85 V to 5.5 V and a digital supply range of 2.7 V to 5.5 V. It consumes 1.2 mW of power and functions within a temperature range of -40°C to +125°C. The component is housed in a 28-lead HTSSOP package.

• Seven-channel 16-bit resolution with integrated PGA
• Sigma-Delta architecture supporting 214.6 S/s sampling rate
• Single-ended input configuration 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 ordering suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure compatibility with system voltage levels, as the analog supply requires 2.85 V minimum while the digital supply starts at 2.7 V. Confirm humidity sensitivity handling procedures are followed during assembly, as indicated in the product attributes.

Analog Front End (AFE) Selection Notes

Select this component for applications requiring multiple single-ended channels with high resolution. The 16-bit resolution and integrated PGA reduce external signal conditioning needs. Verify that the 214.6 S/s maximum data rate meets the system bandwidth requirements. Ensure the PCB layout accommodates the HTSSOP-28 package dimensions and thermal characteristics for operation up to +125°C.

Analog Front End (AFE) Part Context

This part belongs to the LMP90079 series of multi-channel ADCs from Texas Instruments. It is designed for precision applications where channel count and resolution are critical. The NOPB suffix indicates lead-free construction compliant with RoHS standards. It serves as a specialized solution for consolidating multiple sensor signals into a digital interface.

Analog Front End (AFE) Replacement Considerations

Consult Texas Instruments documentation for direct pin-compatible alternatives within the LMP900xx family. Verify electrical parameter equivalence, specifically resolution, channel count, and supply voltage ranges, before substituting.
