Note 1:
Linearity is defined in terms of the H_ to L_ code-dependent resistance.
Note 2:
The DNL and INL are measured with the potentiometer configured as a voltage divider with H_ = V
DD
and L_ = GND. The
wiper terminal is unloaded and measured with an ideal voltmeter.
Note 3:
The DNL and INL are measured with the potentiometer configured as a variable resistor. For the 3-terminal potentiometers
(MAX5451/MAX5453/MAX5455), H_ is unconnected and L_ = GND. For the 2-terminal potentiometers
(MAX5450/MAX5452/MAX5454), L_ = GND. At V
DD
= +5V, the wiper terminal is driven with a source current of 400μA for the
10k
configuration, 80μA for the 50k
configuration, and 40μA for the 100k
configuration. At V
DD
= +3V,
200μA/40μA/20μA for 10k
/50k
/100k
configuration, respectively.
Note 4:
The wiper resistance is the worst value measured by injecting the currents given in Note 3 into W_ with L_ = GND. R

Note 5:
Device draws higher supply current when digital inputs are driven with voltages between 0.3 x V
DD
and 0.7 x V
DD
. (See
Supply Current vs. Digital Input Voltage in the
Typical Operating Characteristics.
)
Note 6:
Wiper-Settling Time is the worst case 0% to 50% rise-time measured between consecutive wiper positions. H_ = V
DD
, L_ =
GND, and the wiper terminal is unloaded and measured with a 10pF oscilloscope probe (see Tap-To-Tap Switching
Transient in the
Typical Operating Characteristics
).
Note 7:
Digital timing is guaranteed by design.
