General Description
APA2020A stereo bridge-tied audio power amplifier various 24-pin power packages including TSSOP-P. When connecting voltage supply APA2020A capable delivering 1.8W/1.2W continuous power channel into loads with less than THD+N respectively. APA2020A simplifies design frees board space other features APA2020A 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 APA2020A 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 APA2020A 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 APA2020A also features shutdown function which keeps supply current only (typ)
