ANPEC APA2020A Stereo Bridge-tied Audio Power Amplifier
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 4ohms/8ohms loads with less than 1% THD+N , respectively. The APA2020A simplifies design and frees up board space for other features . Stereo Audio Power Amplifier for Notebook
Computer The APA2020A also served well in low-voltage applications , which provides 800-mW per channel into 4ohms 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) .
