General Description
The APA2010/2010A is a mono, filter-free Class-D audio
amplifier available in a WLCSP-9 and TDFN3x3-8
packages. The gain can be set by an external input
resistance. High PSRR and differential architecture pro-
vide increased immunity to noise and RF rectification. In
addition to these features, a fast startup time and small
package size make the APA2010/2010A an ideal choice
for both cellular handsets and PDAs.
The APA2010/2010A is capable of driving 1.5W at 5V or
730mW at 3.6V into 8Ω. It is also capable of driving 4Ω.
The APA2010/2010A is designed with a Class-D archi-
tecture and operating with highly efficiency compared
with Class-AB amplifier. It's suitable for power sensitive
application, such as battery powered devices. The filter-
free architecture eliminates the output filter, reduces the
external component count, board area, and system costs,
and simplifies the design.
Moreover, the APA2010/2010A provides thermal and over-
current protections.

Note 1: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination
finish; which are fully compliant with RoHS and compatible with both SnPb and lead-free soldering operations. 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 reserves the right to make changes to improve reliability or manufacturability without notice, and
advise customers to obtain the latest version of relevant information to verify before placing orders.
