Stereo Audio Power Amplifier
Depop Circuitry Integrated Thermal Shutdown Circuitry Integrated Output Power THD+N, VDD=5V W/Ch (typ) into Load W/Ch (typ) into Load Bridge-Tied Load (BTL) Single-Ended (SE) Modes Operation Various 24-Pin Power Packages Available SOP, TSSOP-P Shutdown Control Mode IDD= 0.5µA
General Description
APA2020 stereo bridge-tied audio power amplifier various 24-pin power packages including TSSOP-P. When connecting voltage supply APA2020 capable delivering 1.8W/ 1.2W continuous power channel into loads with less than THD+N respectively. APA2020 simplifies design frees board space other features. APA2020 also served well low-voltage applications which provides 800-mW channel into loads with 3.3V supply voltage. Both depop circuitry thermal shutdown protection circuitry integrated APA2020 that reduces pops clicks noise during power when using shutdown mute modes protects chip from being destroyed over-temperature failure. simplify audio system design notebook computer applications APA2020 combines stereo bridge-tied loads (BTL) mode speaker drive stereo single-end (SE) mode headphone drive into single chip where both modes easily switched SE/BTL input control signal. power sensitive applications APA2020 also features shutdown function which keeps supply current only (typ).
