www.DataSheet4U.com YOUDA INTEGRATED CIRCUIT YD6283 DUAL AUDIO POWER AMPLIFIER-YD6283 DESCRIPTION YD6283 is an audio power IC with built-in two channels developed for portable radio cassette tape recorder. Because of the parts reduction and SIP (Single In line Package), space merit is remarkable. Thermal shut down protection circuit is built in. FEATURES *High Power: Pout（1）=2.5W/CH (Typ.) (Vcc=9V, RL=4Ω, f=1kHz, THD=10%) Pout（2）=4.6W/CH (Typ.) (Vcc=12V, RL=4Ω, f=1kHz, THD=10%) *Low popping noise at power ON *Small quiescent current: Iccq=19mA(Typ.) （Vcc=9V, VIN=0） *Soft clip *Built-in thermal shut down protection circuit *Operation supply voltage range: Vcc=6V～15V *Best for supply voltage：9V, 12V.
