APA2030/1 is a monolithic integrated circuit, which
provides internal gain control, and a stereo bridged
audio power amplifiers capable of producing 2.6W
(1.9W) into 3
with less than 10% (1.0%) THD+N.
By control the two gain setting pins, Gain0 and Gain1,
The amplifier can provide 6dB, 10dB, 15.6dB, and
21.6dB gain settings. The advantage of internal gain
setting can be less components and PCB area. Both
of the depop circuitry and the thermal shutdown pro-
tection circuitry are integrated in APA2030/1, that
reduces pops and clicks noise during power up or
shutdown mode operation. It also improved the power
off pop noise and protects the chip from being de-
stroyed by over temperature and short current failure.
To simplify the audio system design APA2030 com-
bines 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. Besides the multiple input selections is used
for portable audio system. APA2031 eliminates both
input selection and single-end (SE) mode function to
simplifying the design and save the PCB space.
