General Description The APA2056A is a monolithic integrated circuit, which combines a stereo power amplifier and a stereo output capacitor-less headphone amplifier. The headphone amplifier is ground-reference output, and no need the output capacitors for DC blocking. The advantages of eliminating the output capacitor are saving the cost, PCB’ s space and component height. Both the de-pop circuitry and the thermal shutdown protection circuitry are integrated in the APA2056A, which reduces pops and clicks noise during power on/ off and in shutdown mode. Thermal shutdown protects the chip from be.
