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 for the voltage-divider with H_ = VDD and L_ = VSS. The wiper terminal (W_) is unloaded
and measured with a high-input-impedance voltmeter.
Note 3: The DNL and INL are measured with L_ = VSS = 0. For VDD = 5V, the wiper terminal is driven with a current source of IW =
80A for the 50k device and IW = 400A for the 10k device. For VDD = 3V, the wiper terminal is driven with a current
source of IW = 40A for the 50k device and IW = 200A for the 10k 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 (GND +
0.5V). See the Supply Current vs. Digital Input Voltage graph in the
Typical Operating Characteristics.
Note 6: Wiper settling test condition uses the voltage-divider with a 10pF load on W_. Transition code from 0 to 495 and measure
the time from CS going high to the wiper voltage settling to within 0.5% of its final value.
