TIMING CHARACTERISTICS (continued)
(VCC = +2.7V to +5.25V, H = VCC, L = GND, TA = -40°C to +85°C. Typical values are at VCC = +5.0V, TA = +25°C, unless otherwise noted.)
(See Figures 1, 2, 3, and 4).

Note 1: All devices are production tested at TA = +25°C and are guaranteed by design for TA = -40°C to +85°C.
Note 2: The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = VCC and L = GND. The
wiper terminal is unloaded and measured with a high input-impedance voltmeter.
Note 3: The DNL and INL are measured with the potentiometer configured as a variable resistor. H is unconnected and L = GND.
For the +5V condition, the wiper terminal is driven with a source current of 200A and for the +2.7V condition, the wiper ter-
minal is driven with a source current of 100A.
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 (VCC - 0.5V) and (GND +
0.5V). See Supply Current vs. Digital Input Voltage in the Typical Operating Characteristics.
Note 6: Wiper at midscale with a 10pF load, L = 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 0 to 50% rise time measured between consecutive wiper positions. H = VCC, L = GND,
and the wiper terminal is unloaded and measured with a 10pF 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 VCC = 2.7V to the wiper settling to 1 LSB of the final value.
