Overview
The PAM8006ATR is a stereo Class-D audio power amplifier manufactured by Diodes Incorporated. It delivers up to 15W per channel into an 8Ω load with a total harmonic distortion plus noise (THD+N) of 0.2%. The device operates on a supply voltage ranging from 8V to 18V and achieves over 90% efficiency. Key electrical parameters include a signal-to-noise ratio of 90dB, a quiescent current of 16.5mA, and a power supply rejection ratio of -65dB. It utilizes a W-QFN5050-32 package.
Feature Summary
- Features a non-clip power limit function that automatically reduces gain when output power exceeds the set threshold to maintain sound quality.
- Includes comprehensive protection mechanisms such as thermal shutdown, short-circuit protection, overvoltage protection, and under-voltage lockout.
- Incorporates pop noise suppression and a shutdown mode to minimize audible artifacts during power-up and reduce supply current during inactivity.
Applications
- Flat monitors and LCD televisions
- Multi-media speaker systems
- DVD players and game machines
- Boom boxes and musical instruments
Procurement Notes
Verify the component against the official Diodes Incorporated datasheet DS36382 Rev. 2-2 to confirm authenticity. Ensure the ordering suffix 'R' corresponds to the Tape & Reel packaging format. Confirm compliance with RoHS 3 standards and verify the specific lot marking for traceability before finalizing procurement.
Selection Notes
Select this amplifier for applications requiring high efficiency and low external component counts. It is suitable for designs needing differential inputs or single-ended configurations with AC grounding. Consider the W-QFN5050-32 package dimensions and thermal pad requirements for PCB layout optimization.
Part Context
The PAM8006A series represents a line of high-performance CMOS audio amplifiers designed for cost-effective board space savings. The PAM8006ATR variant specifically denotes the reel-packaged version of this stereo Class-D amplifier, intended for automated surface-mount assembly processes.
Replacement Considerations
Consult the manufacturer's documentation for officially confirmed substitute part numbers. Verify pin compatibility and electrical specifications before replacing existing components in established designs.
FAQ
How does the power limit function operate?
The power limit function sets a maximum peak-to-peak output voltage. If the output power exceeds this setting, the amplifier's gain automatically reduces to keep the power below the limit while maintaining sound quality.
What is the recommended capacitor value for the V2P5 terminal?
A minimum of 0.47μF is recommended for the V2P5 capacitor to ensure proper startup timing and filter high-frequency noise from the internal 2.5V bias generator.
