No.1520B LC7816 SANYO cuosic 2-Pole 4-Position Analog Function Switch The LC7816 is a 2-pole 4-position analog function switch with 2obuilt-in cyos analog switches (LC4966 type). A soft touch of a button" enables | Switchover of the input signal source of an audio amplifier. af i Sige es Use : Af ee nee Function switchover of amplifier, receiver, etc. (2polessd, posit tions) Features : od _% » éé 1, Good distortion characterisitc because of bud lt-setjanakég switthes of LC4966 type : Distortion 0.01% max./ Vi=lVyins , Vpp-VeRe15 to39V. 2, Capable of outputting audio muting controY signe Ragggminiptize noise to be generated at the time of switchover, ff gg! 3. Built-in controller for tape monitor switchover (using, 14966 together) . 4. Built-in driver for LED which displayS fust¢tion‘\\rode,“tape monitor mode. 5. Since control input can be operated, from gupply alghé when using dual supplies (+,-), interface with othér circuitsycan be’ achieved easily. 6. Since audio muting control signa” cangbestriggered,"independently from external pin (MUTEin), audio muting ‘@t the) timeof return from backup can be achieved easily. if Fe é¢ 7, Control input pin (RESET) tobe used fox turpiing OFF all analog switches. 8, Backup can be performed easily Because! of CMOS structure.
