PAM8014AZR

Overview

The PAM8014AZR is a mono Class-D audio amplifier manufactured by Diodes Incorporated. It delivers 3.2W output power at 10% THD with a 4Ω load and 5V supply. The device operates on a supply voltage range of 2.5V to 5.5V. It features ultra-low EMI performance, exceeding -20dB better than FCC Class-B limits at 300MHz. Efficiency reaches up to 93% at 2W output into an 8Ω speaker. The unit includes short circuit protection and thermal shutdown capabilities.

Feature Summary

• Filter-less architecture minimizes external components and PCB area while maintaining high performance.
• Ultra-low electromagnetic interference design eliminates noise and RF rectification issues.
• Integrated protection mechanisms include short circuit protection and thermal shutdown for reliability.

Applications

• Cellular Phones
• Smart Phones
• MP4/MP3 Players
• VOIP Devices
• Portable Game Machines

Procurement Notes

Verify the specific ordering suffix AZR corresponds to the U-WLB1313-9 package and tape & reel packing configuration. Confirm compliance with RoHS directives and lead-free requirements as specified in the manufacturer documentation. Ensure compatibility with the required operating temperature range and supply voltage parameters for the intended application environment.

Selection Notes

Select this component for portable applications requiring high efficiency and minimal board space. The differential input helps eliminate noise. Verify that the system can accommodate the filter-less output stage. Consider the shutdown current specification for battery-powered designs. Ensure the load impedance matches the expected output power ratings.

Part Context

This part belongs to the PAM8014 series of audio amplifiers from Diodes Incorporated. It is designed specifically for portable electronic devices where size and power consumption are critical constraints. The series utilizes a CMOS process to achieve high efficiency and low distortion.

Replacement Considerations

Consult official Diodes Incorporated documentation for qualified substitute part numbers. Do not assume cross-compatibility with other manufacturers' products without verifying pinouts, electrical characteristics, and packaging dimensions.

FAQ

What is the default closed-loop gain of the PAM8014?

The default closed-loop gain is 8 V/V (18 dB), determined by internal feedback and input resistors.

How does the PAM8014 handle over-temperature conditions?

The device enters a shutdown state when the die temperature exceeds +150°C. It resumes normal operation once the temperature decreases by +40°C.
