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.

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

3: MCP4018 device only, includes VWZSE and VWFSE.

4: Resistor terminals A, W and B’s polarity with respect to each other is not restricted.

5: This specification by design.

6: Non-linearity is affected by wiper resistance (RW), which changes significantly over voltage and

temperature.

7: POR/BOR is not rate dependent.

8: Supply current is independent of current through the resistor network
