Ordering Information
Temp. Range Package Code Package Code K : SOP R : TSSOP-P * Temp. Range I: - 40 to 85 C Handling Code TU : Tube TR : Tape & Reel TY : Tray * TSSOP-P is a standard TSSOP package with a thermal pad exposure on the bottom of the package. The APA2020A is a stereo bridge-tied audio power amplifier in various 24-pin power packages , includ- ing SOP , TSSOP-P. When connecting to a 5V volt- age supply , the APA2020A is capable of delivering 1.8W/1.2W of continuous RMS power per channel into 4 Ω/8Ω 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 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 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) .
