Muting IC TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic 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 after that supply control signal occurs 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 function.
