General Description
The APA2622 is a stereo, high efficiency, Class-D audio
amplifier and is available in TSSOP-28P and QFN4x4-
28B pins packages.
The Class-D power amplifier has higher efficiency com-
pared to the traditional Class-AB power amplifier. The
filter free Class-D architecture eliminates the external low
pass filters. The internal gain setting can minimize the
external component counts, and for the flexible applica-
tion the gain can be set to 4-step 20, 26, 32, 36dB by gain
control pins (GAIN0 and GAIN1). The AGC function pro-
tects speaker from being out of its power rating but keeps
acceptable performance.
The integration of Class-D power amplifier is a best so-
lution for high efficiency and low BOM costs. The operat-
ing voltage is from 4.5V to 26V. The APA2622 power am-
plifiers are capable of driving 15 W at VDD=16V into 8
speaker, and provides thermal and over-current
protections. It also can detect the DC and then prevent
the speaker voice coil from being detroyed.

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).
