per step)
§ Zero-crossing detection eliminates noise
caused by wiper movement
§ Digital or mechanical pushbutton wiper
control
§ Serial port provides means for setting and
reading both potentiometers wipers
§ 20-pin SOIC and 20-pin TSSOP for surface
mount applications
§ Operating Temperature Range:
-40
°C to +85°C
§ Software and hardware mute
§ Resistance Available: 45 k
