The APA2621 is a stereo, high efficiency, Class-D audio
amplifier available in TSSOP-28P and QFN4x4-28 pins
packages.
The Class-D power amplifier has higher efficiency com-
pare to the tradition Class-AB power amplifier. The filter
free Class-D architecture eliminates the external low pass
filters. The internal gain setting can minimum the exter-
nal component counts, and for the flexible application the
gain can be set to 4-step 20, 26, 32, 36dB by gain control
ins (GAIN0 and GAIN1). The Power limit function can pro-
tection the speaker when output signal excess the
speaker limit rating.
The integration of Class-D power amplifier is a best so-
lution for power efficiency and lower the total BOM costs.
The operating voltage is from 4.5V to 22V. The APA2621
power amplifiers are capable of driving 15 W at VDD=16V
into 8speaker, and provides thermal and over-current
protections. It also has DC protection function to avoid
destroy the speaker voice coil.
It has a frequency selection pin FREQ for customer to
choose suitable frequency (300k, 350k, 400k) for their
system.

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-020D 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).
