Note 1:
The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = V
DD
and L = V
SS
. The
wiper terminal is unloaded.
Note 2:
The DNL and INL are measured with the potentiometer configured as a variable resistor. H is unconnected and L = V
SS
.
The wiper terminal is driven with a source current of 80μA for the 50k
configuration and 40μA for the 100k
configuration.
Note 3:
The wiper resistance is measured assuming the source currents given in Note 2.
Note 4:
The device draws current in excess of the specified supply current when the digital inputs are driven with voltages between
(V
CC
- 0.5V) and (GND + 0.5V). See Supply Current vs. Digital Input Voltage in the
Typical Operating Characteristics
section.
Note 5:
Guaranteed by design and characterization.
