Audio Amplifiers Procurement Notes

Verify the specific suffix TM against TL or other variants to ensure correct package type and reel specifications. Confirm RoHS compliance status through official documentation as required by regional regulations. Check current availability and lead times directly with authorized distributors, as stock levels fluctuate. Ensure the NOPB designation matches the intended non-pb-free requirement for your manufacturing process.

Audio Amplifiers Selection Notes

Select this component when a dual-microphone interface is required in a minimal footprint. The DSBGA-25 package offers a small profile compared to traditional SOIC options. Consider the 2.7 V minimum supply voltage for battery-powered applications. Verify that the thermal performance of the DSBGA-25 case meets the system's heat dissipation requirements under maximum load conditions.

Audio Amplifiers Part Context
