Note 1:
Linearity is defined in terms of the H
X
to L
X
code-dependent resistance.
Note 2:
The DNL and INL are measured with the potentiometer configured as a voltage divider with H
X
= V
DD
and L
X
= 0. 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 potentiometer
(Pot A), H
A
is unconnected and L
A
= 0. For the 2-terminal potentiometer (Pot B), only L
B
= 0. At V
DD
= +5V, the wiper termi-
nal 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 into W
X
, a current I
W
= V
DD
/ R
HL
.
Note 5:
Digital timing is guaranteed by design.
