Standard Operating Conditions (unless otherwise specified)
Operating Temperature
–40°C
TA +125°C (extended)
All parameters apply across the specified operating ranges unless noted.
VDD = +2.7V to 5.5V, 5 k, 10 k, 50 k, 100 k devices.
Typical specifications represent values for VDD = 5.5V, TA = +25°C.

Conditions
Note 1:
Resistance is defined as the resistance between terminal A to terminal B.
2:
INL and DNL are measured at VW with VA = VDD and VB = VSS.
3:
MCP43X1 only.
4:
MCP43X2 only, includes VWZSE and VWFSE.
5:
Resistor terminals A, W and B’s polarity with respect to each other is not restricted.
6:
This specification by design.
7:
Non-linearity is affected by wiper resistance (RW), which changes significantly over voltage and
temperature.
8:
The MCP43X1 is externally connected to match the configurations of the MCP43X2, and then tested.
9:
POR/BOR is not rate dependent.
10: Supply current is independent of current through the resistor network.
