General Description
APA7063 General Description
The APA7063 is a monolithic integrated circuit that provides DC volume control, and a stereo bridged audio power amplifiers capable of producing 1.5W(1.2W) into 8 with less than 10%(1.0%) THD+N. APA7063 provides a volume control pin DC_Vol determines the attenuation of output of the amplifiers. The attenuator range is from 0dB (DC_Vol=0.7VDD) to 105dB (DC_Vol=0V) with 32 steps. Both of the depop circuitry and the thermal shutdown protection circuitry are integrated in the APA7063, that reduces pops and clicks noise during power up and when using the shutdown modes and protects the chip from being destroyed by over temperature failure. To simplify the audio system design applications, the APA7063 combines a stereo bridge-tied loads (BTL) mode for speaker drive and a stereo single-end (SE) mode for headphone drive into a single chip, where both modes are easily switched by the SE/BTL input controlpin signal. The APA7063 also features a shutdown function which keeps the supply current only 0.7A (typ).
