Note 2: The DN and IN are measured with the potentiometer configured as a voltage-divider with H = V CC and = GND. The wiper terminal is unloaded and measured with a high input-impedance voltmeter. Note 3: The DN and IN are measured with the potentiometer configured as a variable resistor. H is unconnected and = GND. For the +5V condition, the wiper terminal is driven with a source current of 2μA and for the +2.7V condition, the wiper terminal is driven with a source current of 1μA. Note 4: The wiper resistance is measured using the source currents given in Note 3. Note 5: The device draws higher supply current when the digital inputs are driven with voltages between (V CC -.5V) and (GND +.5V). See Supply Current vs. Digital Input Voltage in the Typical Operating Characteristics. Note 6: Wiper at midscale with a 1pF load, = GND, an AC source is applied to H, and the output is measured as 3dB lower than the DC W/H value in db. Note 7: Wiper-settling time is the worst-case to 5% rise time measured between consecutive wiper positions. H = V CC, = GND, and the wiper terminal is unloaded and measured with a 1pF oscilloscope probe. See the Tap-to-Tap Switching Transient in the Typical Operating Characteristics section. Note 8: Power-up settling time is measured from the time V CC = 2.7V to the wiper settling to 1 SB of the final value. 4
