Overview
The PAM8302AADCR is a 2.5W Class-D mono audio amplifier manufactured by Diodes Incorporated, housed in an SO-8 surface-mount package. It operates on a single supply voltage ranging from 2.0V to 5.5V and functions within a temperature range of -40°C to +85°C. The device delivers up to 2.5W output power at 10% THD with a 4Ω load and 5V supply. Key electrical characteristics include a quiescent current of 4mA (typical), shutdown current under 1µA, and peak efficiency reaching 88%. It features differential gain of 23.5dB and includes short circuit protection and thermal shutdown.
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
- Low quiescent current and low electromagnetic interference design
Applications
- Portable media players and MP4 devices
- GPS navigation systems
- Portable speaker systems
- Two-way radios
- Hands-free and speaker phones
Procurement Notes
Verify the specific ordering suffix 'DC' corresponds to the SO-8 package type as defined in the manufacturer's documentation. Confirm that the component meets RoHS 3 compliance standards and is halogen-free. Ensure the procurement channel provides valid traceability for electronic components intended for commercial or industrial deployment.
Selection Notes
Select this component when a filterless Class-D mono amplifier is required to minimize PCB area and system cost. It is suitable for designs needing high efficiency and low static current. Verify that the application supports the 2.0V to 5.5V supply range and requires the SO-8 package format. Consider external input capacitor values to set the desired low-frequency response cutoff.
Part Context
This part belongs to the PAM8302A series of audio amplifiers. Other variants in the series include the PAM8302AASCR in MSOP-8 packaging and the PAM8302AAYCR in U-DFN3030-8 packaging. All share identical electrical performance but differ in physical footprint and thermal resistance characteristics.
Replacement Considerations
Direct replacements within the same family include PAM8302AASCR and PAM8302AAYCR. These parts offer identical electrical specifications but utilize different packages (MSOP-8 and U-DFN3030-8 respectively). Substitution requires verifying PCB layout compatibility with the alternative package dimensions.
