BD3490FV
BD3490FV is Sound Processors manufactured by ROHM.
Description
Built in stereo 4 input selectors and volume that there is not an impedance change of a volume terminal. And this is sound processor can realize 2-band equalizer (bass/treble, gain±14d B / 2d B_step) and bass-boost, output-gain, surround by external ponents.
- Features
- Built in stereo 4 input selectors (single end).
- Built-in input gain controller for volume of a portable audio input.
- When the volume setting exchanging, it can use a volume input terminal as a microphone input terminal because there is not an impedance change of a volume input terminal.
- Bi-CMOS process is suitable for the design of low current and low energy. And it provides more quality for Bi-CMOS small scale regulator and heat in a set.
- The package of this IC is SSOP-B28. It gathers a sound input terminals, sound output terminals respectively and it arranges them, to be arranging facilitates the laying-out of PCB pattern and reduces PCB area to one-way in the flow of the signal.
