General Description
APA2069 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 APA2069
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 APA2069, 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, APA2069 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.
