Overview
The PAM8006ATR is a stereo Class-D audio power amplifier from Diodes Incorporated, housed in a W-QFN5050-32 package. It delivers up to 15W per channel into an 8Ω load at 18V supply voltage. The device operates on an 8V to 18V supply and features low THD+N of 0.2% and high efficiency exceeding 90%. Key electrical parameters include a quiescent current of 16.5mA at 12V and 18mA at 18V, with shutdown current under 50µA. It includes integrated protections for overcurrent, thermal, short-circuit, and UVLO conditions.
Feature Summary
- Stereo Class-D architecture delivering high-efficiency audio amplification with minimal external components.
- Integrated power limit function allows adjustable output power control without clipping.
- Comprehensive protection suite including overtemperature, short-circuit, overvoltage, and undervoltage lockout.
- Low noise performance with pop noise suppression and differential input capability.
Applications
- Flat monitors and LCD TVs
- Multi-media speaker systems
- DVD players and game machines
- Boom boxes
- Music instruments
Procurement Notes
Verify the specific ordering suffix 'R' indicates tape and reel packaging containing 3000 units. Confirm the package type is W-QFN5050-32 Standard. Ensure compliance with RoHS 3 and halogen-free requirements if specified by project constraints. Check for automotive qualification status separately as standard parts may not be AEC-Q100 qualified.
Selection Notes
Select this component for applications requiring high output power in a compact form factor. The differential input stage helps reject common-mode noise. Ensure the power supply range matches the 8V to 18V operational limits. Consider the thermal resistance characteristics when designing the PCB layout for adequate heat dissipation.
Part Context
This part belongs to the PAM8006A family of stereo Class-D amplifiers. It is designed for portable and fixed audio applications where space and efficiency are critical. The device integrates analog and digital control circuits within a single small outline package, reducing bill of materials complexity.
Replacement Considerations
No public substitute part numbers are documented in the source material.
FAQ
How is the power limit function configured?
The power limit is set by connecting a resistor from the PL pin to ground. An external capacitor should also be connected from the PL pin to ground.
What is the recommended startup sequence for pop suppression?
For best pop performance, the amplifier should be set in shutdown mode prior to removing the power supply voltage. The SD pin must never be left unconnected.
