PAM8603A (Not Recommended for new design)

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.
