Anpec Electronics APA2051
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.| Part No. | APA2051 |

FEATURES
GENERAL DESCRIPTION
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 during power on/off and in shutdown mode. Thermal shutdown protects the chip from being destroyed by over-temperature failure. To simplify the audio system design in notebook computer applications, the APA2051 provides the internal gain setting, and these features can minimize components and PCB area. The APA2051 is available in TQFN4x4-28 package. This package is characterized by space saving and thermal efficiency.●
