Note 1: 100% production tested at TA = +25°C and TA = +85°C. Guaranteed by design to TA = -40°C.
Note 2: The DNL and INL are measured with the device configured as a voltage-divider with H = VDD and L = VSS. The wiper termi-
nal (W) is unloaded and measured with a high-input-impedance voltmeter.
Note 3: The DNL_R and INL_R are measured with D.N.C. unconnected and L = VSS = 0V. For VDD = +5V, the wiper terminal is dri-
ven with a source current of IW = 80A for the 50kΩ device and 400A for the 10kΩ device. For VDD = +3V, the wiper termi-
nal is driven with a source current of 40A for the 50kΩ device and 200A for the 10kΩ device.
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 (VDD - 0.5V) and (VGND +
0.5V). See Supply Current vs. Digital Input Voltage in the
Typical Operating Characteristics.
Note 6: Wiper settling test condition uses the voltage-divider configuration with a 10pF load on W. Transition code from 00000 00000
to 01111 01111 and measure the time from
CS going high to the wiper voltage settling to within 0.5% of its final value.
