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.
