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 reduces the pops and click noises during power on/off and shutdown mode operation. Both Thermal and over-current protections are integrated to avoid the IC to be destroyed by over temperature and short-circuit. The APA0714 is capable of driving 3W at 5V into 3Ω speaker.

It drives up to 3.6W into an 4Ω speaker (1%THD+N). With 85% typical efficiency, the APA2018 helps extend battery life when playing audio. The built-in boost converter generates a 5.75V supply voltage for the Class-D amplifier when high output power is required. This provides a louder audio output than a stand-alone amplifier directly connected to the battery. During low audio output power periods, the boost converter deactivates and connects VBAT directly to the ClassD amplifier supply, PVDD. This improves overall efficiency. The APA2018 has an integrated low-pass filter to improve the RF rejection and reduce DAC out-of-band noise, increasing the signal-to-noise ratio (SNR).
