BD3490FV - Rohm

BD3490FV Sound Processors

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±14dB / 2dB_step) and bass-boost, output-gain, surround by external components. ●Features „ Built in stereo 4 input selectors (single end). „ Built-in input gain controller for vol.

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 .
