PAM8603A Document number: DSxxxxx Rev. 1 - 2 1 of 16 www.diodes.com November 2012 © Diodes Incorporated PAM8603A A Product Line of Diodes Incorporated ANTI-SATURATION FILTERLESS 3W CLASS-D STEREO AMPLIFIER WITH DC VOLUME CONTROL AND HEADPHONE OUTPUT Description The PAM8603A is a 3W, Class-D audio amplifier with headphone amplifier. Advanced 64-Step DC volume control minimizes external components and allows speaker volume control and headphone volume control. PAM unique antisaturation technology which detects output signal clip due to the over level input signal suppress the output signal clip automatically. Also the antisaturation function can adapt the output clip caused by power supply voltage down with battery. It offers low THD+N, to produce highquality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, without low-pass output filters which will save system cost and PCB area. With the same numbers of external components, the efficiency of the PAM8603A is much better than Class-AB cousins. It can extend the battery life thus be ideal for portable applications. The PAM8603A is available in a SSOP-24 package. Features • 3W Output at 10% THD with a 4Ω Load and 5V Power Supply • Filterless, Low Quiescent Current and Low EMI • Low THD+N • 64-Step DC Volume Control • Headphone Output Function • Unique Anti-Saturation Function • Superior Low Noise • Low Pop Noise • Efficiency Up to 90% • Short Circuit Protection • Thermal Shutdown • Few External Components to Save the Space and Cost • Pb-Free Package Pin Assignments Applications • LCD Monitors / TV Projectors • Notebook Computers • Portable Speakers • Portable DVD Players, Game Machines • VoIP/Speakers Phones
