PAM8902KER

Overview

The PAM8902KER is a Class D audio amplifier manufactured by Diodes Incorporated. It features a single-channel (mono) output configuration housed in a 16-QFN (4x4 mm) package with an exposed pad for thermal management. The device operates on a supply voltage range of 2.7V to 5.5V and supports surface mount installation. Key electrical characteristics include integrated short-circuit and thermal protection mechanisms, ensuring reliable operation within a junction temperature range of -40°C to +85°C.

Feature Summary

• Class D topology for high-efficiency audio amplification
• Integrated short-circuit and thermal protection circuits
• Single-channel mono output design
• Compact 16-pin QFN package with exposed thermal pad

Applications

• Portable consumer electronics requiring efficient audio playback
• Battery-powered devices utilizing low-voltage power supplies
• Embedded audio systems in compact hardware enclosures

Procurement Notes

Verify the specific suffix 'KER' against official Diodes Incorporated documentation to confirm exact tape-and-reel quantities and packaging specifications. Confirm RoHS compliance status and current lifecycle stage, as availability may vary. Ensure the ordering part number matches the required package variant and temperature rating before finalizing procurement orders.

Selection Notes

Select this component when a single-channel, high-efficiency audio solution is required for low-voltage applications. The 16-QFN package suits designs with strict space constraints. Verify that the load impedance and supply voltage align with the 2.7V to 5.5V operating range. Consider the thermal performance of the exposed pad for adequate heat dissipation in enclosed environments.

Part Context

The PAM8902 belongs to the PAM8902A series of audio amplifiers produced by Diodes Incorporated. This family focuses on delivering efficient sound reproduction in portable formats. The device integrates protection features typical of modern Class D amplifiers, targeting cost-sensitive and space-constrained mobile and consumer electronic markets.

Replacement Considerations

Check for direct pin-compatible alternatives within the PAM8902A series or other single-channel Class D amplifiers from Diodes Incorporated. Ensure any substitute matches the 16-QFN footprint and 2.7V-5.5V input range. Verify equivalent thermal and protection specifications before substitution.
