PAM8001

A Product Line of Diodes Incorporated PAM8001 ANTI-SATURATION FILTERLESS 2W CLASS-D STEREO AMPLIFIER WITH DC VOLUME CONTROL AND MAX OUTPUT POWER SETTING Description The PAM8001 is a 2W, class-D audio amplifier. Advanced 64-step DC volume control minimizes external components and allows speaker volume control. PAM unique anti-saturation technology which detects output signal clip due to the over level input signal suppress the output signal clip automatically. Also control the gain for set max power. It can protect low wattage speaker from overdrive damage even same platform with high wattage model. It offers low THD+N, to produce high-quality 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 PAM8001 is much better than class-AB cousins. It can extend the battery life thus be ideal for portable applications. The PAM8001 is available in SSOP-24L and QFN3*3-20L package.
