1.1W to1.5W
Monaural Speaker Amplifier
BD7830NUV
No.10077EAT03
●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 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.
●Features
1) BTL monaural audio power amplifier
2) High power 2.25W 4Ωat Vcc=5V ,THD+N=10%
High power 1.55W 8Ω at Vcc=5V ,THD+N=10%
High power 0.77W 8Ω at Vcc=3.6V ,THD+N=10%
3) Wide operating supply voltage range: 2.4～5.5V
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)
