No.11085EBT09
●Description
BD3460FS, BD3461FS, BD3464FV, BD3465FV is 4ch / 6ch electronic volume which has audio efficiency of the industry
best level. It has 『Outside sound mixing function (with volume)』(BD3461FS, BD3465FV) in favorite channel to mixing of
the portable telephone and car navigation’s guide sound. Also, which has 『Ground isolation amplifier』(BD3460FS,
BD3461FS) when connecting with the outside voice inputs such as portable audio and car navigation. It is lineup and
possible to be chosen to the use by it. Also, Rohm has the volume switching shock sound prevention technique “Advanced
switch”. Therefore, it supports the construct of the high quality car audio space by the simple control.
●Features
1) Reduce switching noise of volume by using advanced switch circuit. (Possible to control all steps)
2) Low distortion (0.0004% typ), Low noise (1.6μVrms)
3) Mixing for external sound monaural 3ch. It is possible that is mixed to front/Rear/Sub output (BD3461FS)
Front/Rear output (BD3465FV) Lch/Rch independently.
4) Built-in 3ch ATT for external sound mixing that can be controlled independently. (BD3461FS, BD3465FV)
5) Built-in buffered stereo ground isolation amplifier inputs, ideal for external input. (BD3460FS, BD3461FS)
6) Bi-CMOS process is suitable for the design of low current and low energy. And it provides more quality
for small scale regulator and heat in a set.
7) Package is SSOP-A24,SSOP-B20. Putting input-terminals together and output-terminals together can make
PCB layout easier and can makes area of PCB smaller.
8) It is possible to control by 3.3V / 5V for I²C BUS.
●Applications
It is the optimal for the car audio. Besides, it is possible to use for the car navigation, audio equipment of mini Compo, micro
Compo, DVD, TV etc with all kinds.
