APPLICATIONS
● Notebook computersFEATURES
● 1) Stereo headphone amplifier that supports mixing input, along with a stereo speaker amplifier (BA7786FP-Y) or BTL monaural speaker amplifier (BA7787FS). 2) Internal anti-pop circuit, to prevent the popping sounds that occur when the power is turned on and off. 3) Internal electronic volume switch and mute circuit. 4) Separate suspend modes for the headphone amplifier and speaker amplifier, for low-power-consumption computers . 5) Two beep input pins, a necessity for notebook computers.●Absolute maximum ratings (Ta = 25°C) Parameter Power supply voltage Power dissipation BA7786FP-Y BA7787FS Symbol VCC Pd Topr Tstg Limits 6 850∗1 600∗2 – 10 ~ + 70 – 55 ~ + 125 Unit V mW °C °C Operating temperature Storage temperature ∗1 Reduced by 6.8mW for each increase in Ta of 1°C over 25°C. ∗2 Reduced by 6.0mW for each increase in Ta of 1°C over 25°C.
