Audio Amplifiers Procurement Notes

Verify the manufacturer designation, as Texas Instruments acquired National Semiconductor's analog business. Confirm that the specific suffix corresponds to the intended package and tape-and-reel specifications. Ensure compliance with RoHS directives by checking the NOPB designation if required. Cross-reference the datasheet revision date to confirm technical parameters match the production batch.

Audio Amplifiers Selection Notes

Select this component when designing low-power audio front-ends requiring integrated amplification. It is appropriate for applications where space is limited due to the small DSBGA footprint. Consider the 56 nV/sqrt Hz noise floor for sensitive audio capture requirements. Verify that the 2 V minimum supply voltage aligns with the system's power budget.

Audio Amplifiers Part Context

This part belongs to the LMV1012 series of analog pre-amplified ICs originally developed by National Semiconductor. Following the acquisition by Texas Instruments, these products are managed under TI's portfolio.
