Procurement Notes

Verify the specific suffix 'D' indicates the correct package type and tape/reel configuration required for your assembly process. Confirm RoHS compliance status through official documentation before procurement. Check for Not Recommended for New Design (NRND) status to ensure long-term availability for production runs.

Selection Notes

Select this component when a stereo headphone amplifier with precise digital volume control is needed. Ensure the system design accommodates the required I2C communication lines. Verify that the power supply voltage range matches the operational requirements of the target application environment.

Part Context

This part belongs to Nisshinbo's audio amplifier lineup, specifically targeting consumer electronics. It replaces older discrete solutions or simpler amplifiers by integrating volume control directly into the IC.
