General Description The APA2051 is a monolithic integrated circuit, which combines a stereo power amplifier and a stereo output capacitor-less headphone amplifier. The stereo power amplifier provides 19-steps gain setting for flexible application. 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 cost, PCB’ s space, and component height. Both the de-pop circuitry and the thermal shutdown protection circuitry are integrated in the APA2051, which reduces pops and clicks noise durin.
