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.
