PAM8902ZER

Overview

The PAM8902ZER is a mono Class-D audio amplifier manufactured by Diodes Incorporated, designed for piezo and ceramic speakers. It delivers a 30 Vpp output from a 2.7V to 5.5V supply. The device features an integrated charge pump boost converter generating a 9V internal supply. It operates in a 16-QFN (4x4) package with surface mount installation.

Feature Summary

Integrated charge pump boost converter generates high voltage for piezo drivers
Anti-saturation technology prevents signal clipping
Low current consumption with automatic standby control

Applications

Piezo speaker amplification
Ceramic sounder driving
Portable alarm systems

Procurement Notes

Verify the specific suffix ZER against the manufacturer's official datasheet to confirm pinout and electrical tolerances. Ensure the component matches the 16-QFN package dimensions. Confirm RoHS compliance status through the latest documentation before integration into designs.

Selection Notes

Select this component when driving piezoelectric or ceramic loads requiring high peak voltage from low supply rails. The integrated boost simplifies design by eliminating external inductors. Verify thermal performance requirements as the device dissipates heat during operation.

Part Context

This part belongs to the PAM8902 series of Class-D audio amplifiers. It is distinct from linear regulators like the MAX8902BATA+T. The series focuses on high-efficiency audio power delivery for small form factor devices using piezo transducers.

Replacement Considerations

Public confirmed substitutes include PAM8902AKER and PAM8902AZER from Diodes Incorporated. These variants share identical functional specifications and pinouts.
