Parameters
Rheostat Integral
Non-linearity
MCP41X1
MCP4XX2
devices only
Resistance is defined as the resistance between terminal A to terminal B.
INL and DNL are measured at V
W
with V
A
= V
DD
and V
B
= V
SS
.
MCP4XX1
only.
MCP4XX2
only, includes V
WZSE
and V
WFSE
.
Resistor terminals A, W and B’s polarity with respect to each other is not restricted.
This specification by design.
Non-linearity is affected by wiper resistance (R
W
), which changes significantly over voltage and
temperature.
8:
The
MCP4XX1
is externally connected to match the configurations of the
MCP41X2
and
MCP42X2,
and
then tested.
9:
POR/BOR is not rate dependent.
10:
Supply current is independent of current through the resistor network
