PAM8965ZLA40-13

Overview

The PAM8965 is a stereo Class-D audio amplifier with an integrated synchronous boost converter. It delivers 2x12W into 4Ω at VBAT=7.4V and 2x8W into 6Ω at VBAT=3.7V. System efficiency reaches 92% at 7.4V. Quiescent current is 10mA, and shutdown current is 0.7μA. The device operates from 2.8V to 8.5V. THD+N is 0.035% at 5W output. Gain is adjustable from 6dB to 26dB in 0.5dB steps via the GAIN pin.

Feature Summary

Integrated synchronous boost converter provides regulated power for high-efficiency operation.
External audio feedback pins enable Kelvin connection to speaker terminals for improved fidelity.
Spread spectrum modulation suppresses EMI across both audio and boost stages.
Automatic gain control manages thermal foldback and non-clipping power limits.

Applications

Portable electronics
Bluetooth speakers
Wireless speakers
Music instruments
Virtual reality 3D active feedbacks

Procurement Notes

Verify the specific suffix ZLA40-13 against Diodes Incorporated documentation to confirm package type and tape/reel specifications. Ensure compatibility with W-QFN5050-40 requirements. Confirm RoHS compliance status for the specific manufacturing lot. Check for any automotive qualification notes if required for the target application environment.

Selection Notes

Select this component for applications requiring high power density and battery efficiency. The integrated boost eliminates external inductors for voltage boosting. Use when low quiescent current is critical for portable devices. Consider the external feedback capability for high-fidelity audio designs. Verify thermal management capabilities given the exposed pad requirement.

Part Context
