LMP90099MHE/NOPB

Analog Front End (AFE) Overview

The LMP90099MHE/NOPB is a 24-bit, seven-channel delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It features an integrated programmable gain amplifier (PGA) and operates with single-ended inputs. The device supports sampling rates up to 214.6 samples per second. It requires an analog supply voltage between 2.85 V and 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-lead HTSSOP package and functions within a temperature range of -40°C to +125°C.

Analog Front End (AFE) Feature Summary

• 24-bit resolution with seven independent channels
• Integrated programmable gain amplifier (PGA)
• Sigma-Delta architecture supporting up to 214.6 S/s sampling rate
• SPI serial interface for data communication

Analog Front End (AFE) Applications

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

Analog Front End (AFE) Procurement Notes

Verify the specific suffix 'MHE' against the manufacturer's official documentation to confirm pinout and package dimensions. Confirm RoHS compliance status through current datasheets as regulatory details may change. Ensure the ordering part number matches the exact package variant required for the PCB layout.

Analog Front End (AFE) Selection Notes

Select this component when high-resolution multi-channel acquisition is required without external amplifiers. The integrated PGA reduces bill-of-materials count. Verify that the input signal range aligns with the available PGA gains. Ensure the system clock frequency supports the desired output data rate of 214.6 S/s.

Analog Front End (AFE) Part Context

This part belongs to the LMP90099 series of low-power, multi-channel ADCs. It shares architectural similarities with other devices in the family but is distinguished by its seven-channel configuration. The 'NOPB' suffix indicates lead-free construction and no special processing options.

Analog Front End (AFE) Replacement Considerations

The LMP90098MHE/NOPB is a verified substitute offering four channels instead of seven. Both devices share the same 24-bit resolution, HTSSOP-28 package, and sigma-delta architecture. Verify channel count requirements before substitution.
