4ch Sound Processor
with Built-in Micro-step Volume
BD34700FV
General Description
The BD34700FV is a 4ch independent volume system.
Micro-step volume can reduce the switching pop noise
when volume changes, so it can achieve a high-quality
set. It is most suitable for subvolume of the multi channel
volume such as AV receivers, but is most suitable for
main volume of simple systems such as 2ch.
Features
Micro-step volume can reduce the switching pop
noise when volume changes.
Micro-step volume can reduce the capacitor for the
DC offset cut
2-wire serial bus control, corresponding to 3.3/5V.
It is controllable to two chips on the same serial bus
by using chip select terminal.
