LMV1032UPX-06/NOPB

Audio Amplifiers Overview

The LMV1032UPX-06/NOPB is a single-channel electret microphone preamplifier manufactured by Texas Instruments, formerly National Semiconductor. It operates within a supply voltage range of 1.65 V to 5.5 V and draws a typical quiescent current of 60 µA. The device features an input voltage noise density of 56 nV/√Hz and functions in Class-AB mode. It is housed in a DSBGA-4 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Audio Amplifiers Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor, when sourcing this component. Confirm the specific suffix '-06' aligns with your required bin or test data if critical for your assembly process. Ensure the DSBGA-4 package footprint matches your PCB design constraints before finalizing procurement orders.

Audio Amplifiers Selection Notes

Select this component when a single-channel, low-noise preamplifier is required for electret microphones in space-constrained designs. The DSBGA-4 package offers a compact solution compared to larger SOIC packages. Consider the 56 nV/√Hz noise specification against system sensitivity requirements. Verify that the 60 µA quiescent current fits within the total power budget of the target application.

Audio Amplifiers Part Context

This part belongs to the LMV1032 series of microphone preamplifiers. It is functionally related to other variants such as the LMV1031, which serves similar audio amplification roles. The component falls under the broader category of audio ICs and analog mixed-signal circuits produced by Texas Instruments following its acquisition of National Semiconductor's semiconductor business.

Audio Amplifiers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative single-channel microphone preamps from the same manufacturer family, ensuring compatibility with the DSBGA-4 package and electrical specifications.
