BD3825FS
Ù¨Description
BD3825FS is an audio signal switch IC used for PAL DVD-Recorders. BD3825FS supports six input lines which are
controlled by the I2C-BUS of video signal LSI BH7624KS2. In addition, BD3825FS has two built-in Function Switch features.
Ù¨Features
1) Vcc = ±5V (for Audio signal), +12V (for Function SW)
Audio SW (C-MOS analog switch configuration)
2) 3 inputs - 1output SW, (2 circuits built-in with MUTE function)
3) 2 inputs - 1output SW, (2 circuits built-in with MUTE function)
4) THD (typ.)
= 0.007%
5) S/N (typ.)
= 90dB
6) Crosstalk (typ.)
= 90dB
7) ON resistance (max.) = 300ȍ
8) 2 Function Switch outputs
Ù¨Applications
DVD-Recorder, STB, etc.
