Overview
The PAM8902KER-P is a mono Class-D audio amplifier with an integrated boost converter, designed for piezo and ceramic speakers. It delivers 30Vpp output from a 2.5V to 5.5V supply. The internal boost converter operates at 1.5MHz, generating up to 17.5V. Gain modes are selectable via the GSET pin: 18dB (GND), 22dB (Floating), or 26dB (AVDD). Boost voltage is configurable via VSET: 8V (GND), 12V (Floating), or 17.5V (AVDD). Shutdown current is less than 1µA. It includes thermal, short-circuit, over-voltage, and under-voltage protection. Package: 16-pin QFN4x4.
Feature Summary
- Integrated boost converter generates high drive voltage for piezo/ceramic loads
- Programmable gain settings of 18dB, 22dB, and 26dB
- Configurable boost output voltage levels
- Low shutdown current consumption
Applications
- Wireless or cellular handsets
- Portable DVD players
- Personal digital assistants (PDAs)
- Electronic dictionaries
- Digital still cameras
Procurement Notes
Verify component authenticity through authorized Diodes Incorporated channels. Confirm package type matches the 16-pin QFN4x4 specification. Check datasheet revision DS36454 Rev. 2-3 for updated electrical characteristics. Ensure application circuitry supports the required input voltage range and external components for the selected gain and boost settings.
Selection Notes
Select this part for applications requiring high peak-to-peak voltage drive for piezoelectric transducers from low voltage supplies. Choose based on required gain configuration and boost voltage level. Consider the QFN4x4 package for space-constrained designs. Verify thermal management requirements given the junction temperature limits and power dissipation characteristics.
Part Context
This component belongs to the PAM8902 product line by Diodes Incorporated. It is specifically engineered as a mono Class-D amplifier optimized for driving piezo and ceramic speakers. The series integrates necessary power conversion stages to achieve high output swing from standard portable device supply voltages.
Replacement Considerations
The datasheet explicitly recommends using PAM8902H instead of the PAM8902 for new designs. Verify if PAM8902H meets all functional and pinout requirements before substitution.
