FEATURES
⋅ High power: supports total output of 30 W+30 W. [EIAJ power] (VCC=14.4 V, THD=30 %, RL=4 Ω) ⋅ Less pop noise. ⋅ Designed for excellent sound quality. (fL<10 Hz, fH=130 kHz) ⋅ Any rise time settable by an external capacitor. ⋅ Standby switch circuit on chip. (microcontroller supported) ⋅ Various protectors on chip. (output-to-ground short/ output-to-VCC short/ load short/ overvoltage/ thermal shutdown circuit) ⋅ The LA4725 is pin-compatible with the LA4728. SANYO: SIP14HZ Specifications MAXIMUM RATINGS
