PAM8013AKR

Overview

The PAM8013AKR is a mono, filter-less Class-D audio amplifier manufactured by Diodes Incorporated. It operates on a supply voltage ranging from 2.8V to 5.5V and delivers up to 3W of output power into a 4Ω load at 5V with 10% THD+N. The device features ultra-low EMI performance, achieving -20dB better than FCC Class-B limits at 300MHz. It incorporates short-circuit protection, thermal shutdown, and pop-and-click suppression circuitry.

Feature Summary

• Filter-less architecture eliminates the need for external output filters, reducing component count and PCB area.
• High efficiency reaches up to 90% at 1W output with an 8Ω speaker load.
• Ultra-low electromagnetic interference (EMI) design minimizes noise in sensitive RF environments.
• Integrated protection mechanisms include short-circuit protection and overtemperature shutdown.

Applications

• Cellular phones and smartphones
• MP4/MP3 media players
• GPS navigation devices
• Digital photo frames
• Portable game machines

Procurement Notes

Verify the specific ordering suffix 'AKR' corresponds to the U-FLGA1515-9 package and tape & reel shipping configuration. Confirm that the component meets RoHS 3 compliance requirements if applicable to your manufacturing standards. Ensure the supplier provides valid traceability documentation for the Diodes Incorporated part number DS36375 Rev. 3.

Selection Notes

Select this component for applications requiring high efficiency and minimal external components in space-constrained designs. The differential input helps eliminate noise and RF rectification issues common in mobile devices. Verify that the operating temperature range of -25°C to +85°C aligns with your system's environmental conditions.

Part Context

The PAM8013 belongs to Diodes Incorporated's line of low-voltage Class-D audio amplifiers. It is designed specifically for portable consumer electronics where battery life and board space are critical constraints. The device utilizes a CMOS process to achieve high performance while maintaining low quiescent current.

Replacement Considerations

FAQ

Does the PAM8013 require an external output filter?

No, the PAM8013 features a filter-less architecture that does not require external output filters, simplifying the application design.

What is the maximum shutdown current for the PAM8013?

The shutdown current is less than 1μA when the SD terminal is driven low.

How does the PAM8013 handle short circuits?

The device includes short-circuit protection circuitry that immediately shuts down the outputs if a short-to-ground or short-to-output condition occurs, reactivating once the fault is removed.
