Note 1: Parameters are 100% production tested at +85°C and limits through the temperature range are guaranteed by design.
Note 2: Tap-to-tap tolerance is the error in voltage change between successive tap positions.
Note 3: Supply current measured while wiper position is fixed.
Note 4: One button pressed.
