APA2068  
Stereo 2.6W Audio Power Amplifier (with DC_Volume Control)  
General Description  
Features  
·
·
Low Operating Current with 9mA  
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)into4Wwithlessthan10%(1.0%)THD+N.  
Theattenuatorrangeof the volumecontrol inAPA2068  
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. 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 simplify the  
audio system design, APA2068 combines a stereo  
bridge-tied loads (BTL) mode for speaker drive and a  
stereo single-end(SE) modefor headphonedrive into  
a single chip, where both modes are easily switched  
by the SE/BTL input control pin signal.
