Simplified Application Circuit
The APA3176 is a digital input, stereo, high efficiency,
Class-D audio amplifier and is available in QFN4x4-28A
and TSSOP-28P pins packages.
The APA3176 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 APA3176 is a slave device receiving clocks from ex-
ternal source, and the Class-Ds PWM switching fre-
quency is 352.8kHz for the sampling rate 44.1kHz or 384
kHz for sampling 48kHz, depend on the input signals
sampling rate.

Note : ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for
MSL classification at lead-free peak reflow temperature. ANPEC defines Greento mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
