PAM8002AZN

Overview

The PAM8002AZN is a mono 2.0W anti-saturation Class-D audio power amplifier manufactured by Diodes Incorporated. It operates from a single supply voltage ranging from 2.5V to 5.5V. The device delivers 2.0W of continuous output power into a 4Ω load at 5V with less than 10% Total Harmonic Distortion plus Noise (THD+N). It features an integrated anti-saturation circuit that maintains high output power even under low supply voltage conditions, such as during battery discharge. The amplifier includes built-in short-circuit protection and thermal shutdown for robust operation.

Feature Summary

• Integrated anti-saturation circuitry prevents output clipping during low supply voltages
• Class-D topology ensures high energy efficiency suitable for portable devices
• Built-in short-circuit and thermal protection mechanisms enhance reliability

Applications

• Portable media players
• Mobile phones and smartphones
• Personal digital assistants (PDAs)
• MP3 players

Procurement Notes

Verify the component status as obsolete or end-of-life through official manufacturer channels before procurement planning. Confirm RoHS compliance details directly with the supplier documentation. Ensure the specific package variant matches design requirements. Cross-reference part numbers carefully to avoid counterfeit components. Request original datasheets for accurate electrical specifications.

Selection Notes

Select this component for applications requiring high-efficiency audio amplification in space-constrained portable electronics. The wide input voltage range supports various battery configurations. Consider the anti-saturation feature if operating near minimum supply thresholds. Evaluate thermal performance based on PCB layout and ambient conditions. Verify compatibility with existing audio codec interfaces.
