BD3870FS

Sound Processors for BOOM BOX / Mini-component Stereo Sound Processors with Built-in 2-band Equalizers BD3870FS,BD3871FS,BD3872FS,BD3873FS No.10086EAT02 ●Description The Sound Pr ocessor with built-in 2 Band Equalizer, incorporates functions required for BOOM BOX and mi ni-component systems, such as input se lector, input gai n amp, vol ume, surroun d, tone (b ass, treble), an d lo ud speaker e qualizer (BD3872FS only). These functions can be controlled through the two-wire serial control. ●Features 1) Using external components, center frequencies and Q factors of the bass characteristics are flexible. 2) Providing a mute switch onto one of the input pins allows cross-talk suppression. 3) A surround function can be constructed without external components. 4) Energy-saving design resulting in low current consumption, by utilizing the BiCMOS process ●Applications BOOM BOX, mini-audio systems, and micro-audio systems. ●Line up matrix Parameter Input Gain Loud Speaker Equalizer (SEQ) Input Selector Volume Equalizer Surround Serial Control Package SSOP-A24 ●Absolute maximum ratings (Ta=25℃) Prameter S Power Supply Voltage Power Dissipation Operating Temperature Range Storage Temperature Range ymbol Vcc Pd Topr Tstg Ratings BD3870FS 10 800 *1 -25 to +75 -55 to +125 BD3871FS 10 800 *1 -25 to +75 -55 to +125 BD3873FS 10 800 *1 -25 to +75 -55 to +125 BD3872FS 10 950 *2 -25 to +75 -55 to +125 Unit V mW ℃ ℃ BD3870FS BD38 0, 6, 12, 18dB No Three inputs 0 to -87dB/ 1dB step, -dB 2 band...
