Copyright  ANPEC Electronics Corp. Rev.

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 8 Ω . It is also capable of driving 4 Ω . 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. Features General Description

Ordering and Marking Information 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).
