Overview
The PAM8603MNHR is a two-channel stereo Class-D audio amplifier manufactured by Diodes Incorporated. It delivers 3 W of output power into a 4 Ohm load with a total harmonic distortion plus noise of 0.15%. The device operates within a supply voltage range of 2.8 V to 5.5 V and draws a typical operating current of 13.5 mA. It supports an extended operating temperature range from -40°C to +85°C and features a shutdown function for power management. The component is housed in an SSOP-24 surface-mount package.
Feature Summary
- Filterless Class-D architecture eliminates the need for external output filters, reducing component count and board space.
- Stereo configuration provides dual-channel amplification for high-fidelity audio reproduction.
- Integrated shutdown mode enables effective power conservation during idle periods.
Applications
- Portable multimedia devices requiring compact audio solutions
- Consumer electronics utilizing low-voltage power supplies
- Battery-operated audio equipment prioritizing efficiency
Procurement Notes
Verify the specific suffix MNHR against official Diodes Incorporated documentation to confirm reel packaging specifications and moisture sensitivity levels. Ensure compatibility with standard SSOP-24 footprint designs. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before final procurement integration.
Selection Notes
Select this component when a filterless stereo solution is required for 4 Ohm loads. Compare the 2.8 V minimum supply requirement against system constraints. Evaluate the SSOP-24 package dimensions against available PCB real estate. Consider the 13.5 mA quiescent current for battery life calculations relative to alternative Class-D options.
Part Context
This part belongs to the PAM8603 series of audio amplifiers. It shares core performance characteristics with variants like the PAM8603MDER but differs in packaging and reel configuration. The series represents Diodes Incorporated's approach to efficient, low-component-count audio amplification for portable applications.
Replacement Considerations
The PAM8603MDER serves as a functional substitute within the same series. Verify that the SSOP-24 package remains compatible with the target design. Confirm that electrical parameters such as output power and supply voltage ranges remain identical across both part numbers.
