The APA4863 is a stereo bridge-tied audio power ampli-
fier in various power packages, including SOP, TSSOP,
and TSSOP-P. When connecting to a 5V voltage supply,
the APA4863 is capable of delivering 2.2W/1.8W/1.2W of
continuous RMS power per channel into 3Ω/4Ω/8Ω
bridge-tied loads with less than 1% THD+N respectively.
When APA4863 operates in the single-ended load, it is
capable of delivering 90mW of continuous RMS power
per channel into 32Ω load. The APA4863 simplifies de-
sign and frees up board space for other features.
The APA4863 also served well in low-voltage
applications, which provides 750mW (1% THD+N) per
channel into 4Ω loads with a 3.3V supply voltage. Both of
the depop circuitry and the thermal shutdown protection
circuitry are integrated in the APA4863, which reduces
pops and clicks noise during power up and when using
the shutdown mode and protects the chip from being
destroyed by over-temperature failure. To simplify the au-
dio system design in notebook computer applications,
the APA4863 combines a stereo bridge-tied loads mode
for speaker drive and a stereo single-end mode for head-
phone drive into a single chip, where both modes are
easily switched by the HP-IN input control pin signal. For
power sensitive applications, the APA4863 also features
a shutdown function which keeps the supply current only
0.5 µA (typ.).

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
