Anpec Electronics APA2068
APA2068 is a monolithic integrated circuit, which provides precise DC volume control, and a stereo bridged audio power amplifiers capable of producing 2.6W (1.8W) into 4Ω with less than 10% (1.0%) THD+N. The attenuator range of the volume control in APA2068 is from 20dB (DC_Vol=0V) to -80dB (DC_Vol=3.54V) with 32 steps. The advantage of internal gain setting can be less components and PCB area.| Part No. | APA2068 |

GENERAL DESCRIPTION
Both of the depop circuitry and the thermal shutdown protection circuitry are integrated in APA2068, that reduce pops and clicks noise during power up or shutdown mode operation. It also improves the power off pop noise and protects the chip from being destroyed by over temperature and short current failure. To...
