Overview
The PAM8003DR_B02 is a filterless Class-D stereo audio amplifier manufactured by Diodes Incorporated. It delivers 2.5W output power at 10% THD+N with a 5V supply and 5Ω load. The device operates on a supply voltage range of 2.5V to 5.5V and functions within an ambient temperature range of -40°C to +85°C. It features low quiescent current, low EMI, and includes short circuit protection and thermal shutdown capabilities.
Feature Summary
- Filterless architecture eliminates the need for external low-pass output filters, reducing system cost and PCB area.
- Includes 64-step DC volume control for precise gain adjustment.
- Incorporates short circuit protection and thermal shutdown to prevent device damage under fault conditions.
Applications
- LCD Monitors / TVs
- Notebook Computers
- Portable Speakers
- Portable DVD Players, Game Machines
Procurement Notes
Verify that the B02 suffix corresponds to the specific marking or tape-and-reel configuration defined in the official datasheet. Confirm package type matches SO-16 requirements. Ensure environmental compliance aligns with RoHS and Green Package standards as documented by the manufacturer.
Selection Notes
Select this component for portable applications requiring high efficiency compared to Class-AB amplifiers. Consider its low quiescent current for battery life extension. Verify input signal levels to avoid clipping due to high gain. Ensure adequate power supply decoupling to maintain low THD and PSRR performance.
Part Context
