The APA4835 is a monolithic integrated circuit , which
provides DC volume control , and a stereo bridged
audio power amplifiers capable of producing 2.8W
(2.2W) into 3Ω with less than 10% (1.0%) THD+N.
APA4835 includes a DC volume control , stereo
bridge-tied and single-ended audio power amplifiers
, stereo docking outputs , and a selectable gain control , that makes it optimally fittable for notebook PC
, multimedia monitors , and other portable
applications. The attenuator range of the volume
control in APA4835 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 APA4835 , that reduces
pops and clicks noise during power up or shutdown
mode operation , and protects the chip from being
destroyed by over temperature failure. To simplify
the audio system design , APA4835 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. Besides the low supply current design to increase the
efficiency of the amplifiers , APA4835 also features a
shutdown function which keeps the supply current
only 0.7µA (typ).
