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).
