AC/DC CHARACTERISTICS (CONTINUED)

DC Characteristics

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 kΩ, 10 kΩ, 50 kΩ, 100 kΩ 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.

INL and DNL are measured at VW with VA = VDD and VB = VSS.

MCP4XX1

only.

MCP4XX2

only, includes VWZSE and VWFSE.

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 (RW), which changes significantly over voltage and

temperature.

The MCP4XX1 is externally connected to match the configurations of the MCP41X2 and MCP42X2, and

then tested.

POR/BOR is not rate dependent.

10:

Supply current is independent of current through the resistor network
