BD3491FS

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. Typical Application Circuit Key Specification Current upon no signal: Total Harmonic Distortion: Maximum Input Voltage: Crosstalk between Selectors: Volume Control Range: Output Noise Voltage: Residual Output Noise Voltage: Operating Temperature Range: 7mA(typ) 0.002%(typ) 2.4Vrms(typ) 100dB(typ) 0dB to -87dB 5µVrms(typ) 5µVrms(typ) -40℃ to +85℃ Package SSOP-A32 W(typ) x D(typ) x H(max) 13.60mm x 7.80mm x...
