General Description

Ordering and Marking Information

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 4W withlessthan 10%(1.0%)THD+N.

The attenuator range of 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) mode for headphone drive into

a single chip, where both modes are easily switched

by the SE/BTL input control pin signal.
