TA8194Z

The TA8194Z is a muting IC to prevent the "POP" noise made at time of power ON and OFF of audio equipments.This IC has 4 sensor terminals,muting control terminal and supply control terminal.In case of sensing voltage rising,muting control signal occurs and that supply control signal occurse and muting signal maintains for 1s.In case of sensing voltage setting,muting control signal occurs and after that supply control signal stops.This IC also has manual muting terminal and protection functions.

Features of the TA8194Z are:(1)4 sensor terminals : VCC,B1,B2,B3;(2)muting circuit control signal output;(3)power supply circuit control signal output;(4)manual muting control terminal;(5)protection function terminal;(6)operating supply voltage range : VCC(opr)=8 to 18V(Ta=25).

The maximum ratings of the TA8194Z can be summarized as:(1):the characteristic is supply voltage,the symbol is VCC,the rating is 25,the unit is V;(2):the characteristic is power dissipation,the symbol is PD,the rating is 750,the unit is mW;(4):the characteristic is operating temperature,the symbol is Topr,the rating is -30 to 85,the unit is ;(5):the characteristic is storage temperature,the symbol is Tstg,the rating is -55 to 150,the unit is .
