General Description
The APA2010B is a mono, filter-free Class-D audio am-
plifier available in WLCSP-9 packages. The gain can be
set by an external input resistance. High PSRR and dif-
ferential architecture provide increased immunity to noise
and RF rectification. In addition to these features, a fast
startup time and small package size make the APA2010B
an ideal choice for both cellular handsets and PDAs.
The APA2010B is capable of driving 1.5W at 5V or 730mW
at 3.6V into 8Ω. It is also capable of driving 4Ω. The
APA2010B is designed with a Class-D architecture 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 compo-
nent count, board area, and system costs, and simplifies
the design.
Moreover, the APA2010B provides thermal and over-cur-
rent protections.
Applications
• Mobile Phones
• Handsets
• PDAs
• Portable multimedia devices
