描述 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.
