3W Mono Fully Differential Audio Power Amplifier

APA0715

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 3

Ω
