BD3490FV

Datasheet Analog Audio Processors Sound Processors with Built-in Surround Sound Function BD3490FV ●General 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±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 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. ●Key Specifications „ Current upon no signal: „ Total harmonic distortion: „ Maximum input voltage: „ Cross-talk between selectors: „ Volume Control range: „ Output noise voltage: „ Residual output noise voltage: „ Operating Range of Temperature: 7mA(Typ.) 0.002%(Typ.) 2.4Vrms(Typ.) 100dB(Typ.) 0dB to -87dB 5μVrms(Typ.) 5μVrms(Typ.) -40℃ to +85℃ ●package(s) SSOP-B28 W(Typ.) x D(Typ.) x H(Max.) 10.00m...
