The APA3169 is a digital input, stereo, high efficiency,
Class-D audio amplifier available in a TQFP7x7-48P
package.
The APA3169 accepts the digital serial audio data and
using the digital audio processor to convert the audio
data becomes the stereo Class-D output speaker
amplifier. This provides the seamless integration between
the codec and the speaker amplifier.
The APA3169 is a slave device receiving clocks from ex-
ternal source, and the Class-D’s PWM switching fre-
quency is 352.8kHz for the sampling rate 44.1kHz or 384
kHz for sampling 48kHz, depend on the input signal’s
sampling rate.
