General Description
The APA2011/2011A is a mono, filter-free Class-D audio
amplifier available in WLCSP1.5x1.5-9 or TDFN3x3-8
package.
The default gains without the external input resistor is
27dB. Besides, the gain can be low down by external
input resistance. APA2011 provides an Dynamic-Range-
Control (DRC) function, and this function can low down
the dynamic range for large input signal. APA2011 can
provide maximun 15dB gain control. APA2011A can pro-
vide maximum 15dB gain decrease for non-clipping
function, and this function can avoid output signal clipping.
High PSRR and differential architecture provide increased
immunity to noise and RF rectification. In addition to these
features, a fast start-up time and small package size
make the APA2011/2011A an ideal choice for portable
devices.
The APA2011/2011A is capable of driving 1.6W at 5V or
0.8W at 3.6V into 8Ω. It is also capable of driving 4Ω. The
APA2011/2011A is designed with a Class-D architecture
and operating with highly efficiency compared with Class-
AB amplifier. It’ suitable for power sensitive application,
s
such as battery-powered devices. The filter-free architec-
ture eliminates the output filter, reduces the external com-
ponent count, board area, and system costs, and simpli-
fies the design.
Moreover, the APA2011/2011A provides thermal and short
circuit protection.

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 “Green” to 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).

Note 2: Please refer to “ Layout Recommendation”, the Thermal Pad on the bottom of the IC should soldered directly to the PCB’
s
Thermal Pad area that with several thermal vias connect to the ground plan, and the PCB is a 2-layer, 5-inch square area with 2oz
copper thickness.
Note 3: The case temperature is measured at the center of the exposed pad on the underside of the TDFN3x3-8 package.
