GENERAL DESCRIPTION
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...
