Overview
Datasheet Analog Sound Processor series Sound Processor with Built-in Surround Sound Function BD3491FS General Description Built in stereo 6 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 BassBoost, Output gain, Surround by external components.
Features Equipped with 6 single ended stereo input selectors Built-in input gain controller suitable for mobile audio.
Volume input terminal can be used as a microphone input terminal since its impedance remains constant even if volume setting is changed.
Bi-CMOS process is suitable for the design of low current and low energy.
It also provides more quality for Bi-CMOS small scale regulator and heat in a set.
The package of this IC is SSOP-A32.
Sound input terminals and output terminals arrangement is optimized for easy and fast layout of PCB pattern.
At the same time, it minimizes PCB area.
Applications Suitable for mini-components or micro components.
Used for audio equipment of TV, DVD, etc.
