APA2020
Stereo 2-W Audio Power Amplifier
Features
General Description
•
Depop Circuitry Integrated
•
Thermal Shutdown Circuitry Integrated
•
Output Power at 1% THD+N, VDD=5V
The APA2020 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 APA2020 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 APA2020 simplifies design and frees up board
space for other features.
- 1.8 W/Ch (typ) into a 4 Ω Load
- 1.2 W/Ch (typ) into a 8 Ω Load
•
Bridge-Tied Load (BTL) or Single-Ended
The APA2020 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 APA2020 , 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 APA2020 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 APA2020 also
features a shutdown function which keeps the supply
current only 0.5 µA (typ).
