General Description
The APA0714 is a Mono, fully differential Class-AB audio
amplifier which can operate with supply voltage from 2.4V
to 5V and is available in MSOP8, MSOP8P, or TDFN3x3-8
package.
The built-in feedback resistors can minimize the external
component count and save the PCB space. High PSRR
and fully differential architecture increase immunity to
noise and RF rectification. In addition to these features, a
short startup time and small package size make the
APA0714 an ideal choice for Mobil Phones and Portable
Devices.
The APA0714 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 to be de-
stroyed by over temperature and short-circuit.
The APA0714 is capable of driving 3W at 5V into 3Ω
speaker.
