The AT8684 is a versatile attenuator that permits easy in-line switch installation and flexible application. Type of external single-pole switch the user supplies determines muting function; closed contact causes muting. Use for on/off, push-to-talk, push-to-mute, etc. (Additional, isolated poles on the switch may be used to control logic-level DC circuits.)
