General Description

The APA2020A is a stereo bridge-tied audio power
amplifier in various 24-pin power packages , includ­ing SOP , TSSOP-P. When connecting to a 5V volt­age supply , the APA2020A is capable of delivering

1.8W/1.2W of continuous RMS power per channel
into 4Ω/8Ω loads with less than 1% THD+N ,
respectively. The APA2020A simplifies design and
frees up board space for other features .

The APA2020A also served well in low-voltage
applications , which provides 800-mW 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 APA2020A , that reduces
pops and clicks noise during power up and when
using the shutdown or mute modes and protects the
chip from being destroyed by over-temperature
failure.
To simplify the audio system design in notebook
computer applications , the APA2020A 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 . For
power sensitive applications , the APA2020A also
features a shutdown function which keeps the supply
current only 0.5 µA (typ) .
