Overview
The PAM8902AZER-P is a mono Class-D audio amplifier manufactured by Diodes Incorporated, designed specifically for piezoelectric and ceramic speakers. It supports a supply voltage range of 2.7V to 5.5V and delivers a peak-to-peak output voltage of 30V. The device operates within an ambient temperature range of -40°C to +85°C and is housed in a 16-QFN (4x4) package with a bare pad. Key electrical features include integrated short-circuit and thermal protection mechanisms.
Feature Summary
- Optimized for driving high-voltage piezoelectric and ceramic speaker loads
- Includes anti-saturation control functionality
- Integrates short-circuit and thermal protection circuits
Applications
- Piezoelectric buzzer drivers
- Ceramic speaker amplification
- Portable electronic devices requiring compact audio output
Procurement Notes
Verify the exact suffix against official Diodes Incorporated documentation, as standard listings typically reference PAM8902AKER or PAM8902AZER. Confirm component status, as this series has been subject to End-of-Life notices. Ensure the specific part number matches the required packaging format and revision level before procurement.
Selection Notes
Select this component when designing circuits for piezo or ceramic transducers requiring high voltage swing from low supply voltages. The 16-QFN package suits space-constrained applications. Verify that the load impedance and capacitance characteristics of the target speaker are compatible with the amplifier's output stage capabilities.
Part Context
This component belongs to the PAM8902 series of mono Class-D audio amplifiers. It is distinct from stereo variants like the PAM8406. The series is engineered for efficiency and reliability in driving non-standard audio loads such as piezoelectric elements, differing from conventional dynamic speaker amplifiers.
Replacement Considerations
Official substitutes within the same family include PAM8902A and PAM8902H. Cross-manufacturer replacements such as Texas Instruments TPA2100P1 may offer similar functionality but require verification of pin compatibility and performance specifications.
