APA0715
3W Mono Fully Differential Audio Power Amplifier
Features
General Description
The APA0715 is a Mono, fully differential Class-AB audio
amplifier which can operate with supply voltage from 2.4V
to 5V and is available in a MSOP8, MSOP8P, or TDFN3x3-
8 package.
High PSRR and fully differential architecture increase im-
munity to noise and RF rectification. In addition to these
features, a short startup time and small package size
make the APA0715 an ideal choice for Mobil Phones and
Portable Devices.
The APA0715 also integrates the de-pop circuitry that re-
duces the pops and click noises during power on/off and
shutdown mode operation. Both Thermal and over-cur-
rent protections are integrated to avoid the IC being de-
stroyed by over temperature and short-circuit.
The APA0715 is capable of driving 3W at 5V into 3Ω
speaker.

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-
020C 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
ThermalPad 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 Thermal Pad on the underside of the MSOP-8P and TDFN3x3-8
package.
