Overview
The PAM8302AASCR is a 2.5W Class-D mono audio amplifier manufactured by Diodes Incorporated in an MSOP-8 package. It operates on a single supply voltage ranging from 2.0V to 5.5V and achieves peak efficiency up to 88%. The device delivers 2.5W output power at 10% THD+N with a 4Ω load and 5V supply. It features low quiescent current, short circuit protection, thermal shutdown, and requires minimal external components.
Feature Summary
- Filterless architecture allows direct speaker driving without low-pass output filters
- High efficiency up to 88% optimizes battery life for portable applications
- Integrated short circuit protection and thermal shutdown ensure operational safety
Applications
- Portable media players (PMP/MP4)
- GPS navigation systems
- Portable speakers
- Two-way radios
- Hands-free and speaker phones
Procurement Notes
Verify the component matches the exact Diodes Incorporated part number PAM8302AASCR. Confirm the package type is MSOP-8 and that it meets RoHS 3 compliance standards. Ensure the supplier provides valid traceability documentation. Check for moisture sensitivity level requirements during storage and handling.
Selection Notes
Select this amplifier for designs requiring high efficiency and minimal PCB space. It is suitable for battery-powered devices where low quiescent current extends operational time. Verify that the application supports the differential input configuration and the required supply voltage range of 2.0V to 5.5V.
Part Context
This component belongs to the PAM8302A series of filterless Class-D mono audio amplifiers. It is designed as a cost-effective alternative to Class-AB amplifiers, offering superior efficiency with fewer external components. The series includes variants in SO-8 and U-DFN3030-8 packages.
Replacement Considerations
Direct substitutes include PAM8302AADCR (SO-8) and PAM8302AAYCR (U-DFN3030-8). These share identical electrical characteristics but differ in physical package dimensions and pinout compatibility.
FAQ
Does the PAM8302A require an output filter?
No, the PAM8302A utilizes a filterless architecture that allows it to drive speakers directly without the need for low-pass output filters.
What is the maximum supply voltage?
The recommended operating supply voltage range is 2.0V to 5.5V, with an absolute maximum rating of 6.0V at no input signal.
