Note 1: If an RIN other than 300 Ω is used, the volume attenuation and attack/release times change.

Note 2: In the standard application a capacitor is connected between Pin 13 and VSS. Attack is the term used to describe the action of changing the

unit from ‘mute off’ to ’mute on’. Release is the term used to describe the action of changing the unit from ‘mute on’ to ‘mute off’. The standard

timing control capacitance is 0.047 µF.

Note 3: Power dissipation is 350 mW when mounted as recommended. Derate at 2.8 mW/°C for operation above 25°C.
