BD3490FV-E2

●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. 

●Applications 

„ It is the optimal for the mini compo or micro compo. Besides, it is possible to use for the audio equipment of TV, DVD etc with all kinds

●Key Specifications 

„ Current upon no signal: 7mA(Typ.) 

„ Total harmonic distortion: 0.002%(Typ.) 

„ Maximum input voltage: 2.4Vrms(Typ.)

 „ Cross-talk between selectors: 100dB(Typ.) 

„ Volume Control range: 0dB to -87dB 

„ Output noise voltage: 5μVrms(Typ.) 

„ Residual output noise voltage: 5μVrms(Typ.) 

„ Operating Range of Temperature: -40℃ to +85℃
