LMV1026UR/NOPB

Audio Amplifiers Overview

The LMV1026UR/NOPB is a microphone pre-amplifier integrated circuit manufactured by Texas Instruments. It features a Pulse Density Modulation (PDM) output designed specifically for electret microphones. The device operates within a supply voltage range of 2.7 V to 5.5 V and functions reliably across an operating temperature range of -40°C to +85°C. It utilizes a small DSBGA-4 package suitable for surface-mount applications.

Audio Amplifiers Feature Summary

• Integrates a pre-amplifier with direct Pulse Density Modulation (PDM) digital output capability
• Optimized for interfacing directly with electret condenser microphones
• Supports single-supply operation within a low voltage range

Audio Amplifiers Applications

• Digital audio input stages in mobile devices
• Voice recognition systems requiring direct digital microphone interface
• Portable consumer electronics with space-constrained PCB layouts

Audio Amplifiers Procurement Notes

Verify the specific suffix UR/NOPB against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the design supports PDM signal processing requirements, as this component outputs digital density data rather than analog voltage. Confirm availability through authorized distributors given potential lifecycle changes.

Audio Amplifiers Selection Notes

Select this component when a digital output from the microphone stage is required to simplify system architecture. It eliminates the need for external analog-to-digital converters for the audio path. Consider the DSBGA-4 package size constraints during layout. Verify that the host processor can decode PDM signals if not using a dedicated codec.

Audio Amplifiers Part Context

This part belongs to the LMV10xx series of microphone amplifiers from Texas Instruments. It serves as a bridge between analog acoustic sensors and digital processing units. The NOPB suffix indicates lead-free construction compliant with environmental standards. It replaces older National Semiconductor designs within the TI portfolio.

Audio Amplifiers Replacement Considerations

Direct substitutes include other LMV1026 variants such as LMV1026URX or LMV1026UR. Cross-reference with LMV1022 or LMV1032 series parts if different gain configurations or analog outputs are acceptable. Verify package footprint compatibility before substitution.
