Note 1: If a RIN other that 3 kΩ is used, then the volume attenuation and attack/release time changes.

Note 2: Attack is an action that changes to “mute on” from “mute off”, and release is action that changes to “mute off” from “mute on”.

Standard capacity for the timing control is 0.22 µF.

Note 3: Power dissipation is 200 mW when mounted as recommended. Derate at 1.6 mW/°C for operation above 25°C.
