Monaural Speaker Amplifier
BD7830NUV
No.10077EAT03
âDescription
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 µA, 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.
âFeatures
1) BTL monaural audio power amplifier
2) High power 2.25W 4â¦at 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: 2.4ï½5.5V
4) Low standby current: 0µA
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)
