Class-AB Speaker Amplifiers 1.1W to1.5W Monaural Speaker Amplifier No.10077EAT03 BD7830NUV Description The BD7830NUV is a monaural speaker amplifier that operates at low voltage and was developed for portable navigation and mobile audio products. When in standby mode, its current consumption is 0 A, and since it switches quickly and quietly from standby to ON, it is especially well suited for applications where there is frequent switching between standby and ON. Features 1) BTL monaural audio power amplifier 2) High power 2.25W 4at Vcc=5V ,THD+N=10% High power 1.55W 8 at Vcc=5V ,THD+N=10% High power 0.77W 8 at Vcc=3.6V ,THD+N=10% 3) Wide operating supply voltage range: 2.45.5V 4) Low standby current: 0A 5) Fast turn on/off time: 46msec 6) Built-in Fade-in/out function 7) Built-in anti-pop function 8) Built-in thermal shutdown function 9) Very small package (VSON008V2030) Applications Mobile phones, Mobile electronics applications Absolute Maximum Ratings(Ta=+25) Parameter Symbol Ratings Unit Supply voltage V 6.0 V CC *1 Power dissipation Pd 530 mW Storage temperature range Tstg -55+150 STBY input range V -0.1Vcc+0.1 V STBY *1 ROHM standard one layer board (70mm70mm1.6mmt) mounted, deratings is done at 4.24mW/ above Ta=+25.
