MCP47FXBX4/8
DC CHARACTERISTICS (CONTINUED)
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, VREF= +2.048V to VDD, VSS = 0V, Gx = 0, RL = 5 k from VOUT to GND, CL = 100 pF.
Typical specifications represent values for VDD = 5.5V, TA = +25°C.

(7Fh, 1FFh or 7FFh) V 1.8V VDD 5.5V(1) Note 1 This parameter is ensured by design. Note 2 This parameter is ensured by characterization. Note 6 Resistance is defined as the resistance between the VREF pin (mode VRnB:VRnA = 10) to VSS pin. For
octal-channel devices (MCP47FXBX8), this is the effective resistance of each resistor ladder. The
resistance measurement is one of the two resistor ladders measured in parallel. Note 11 Variation of one output voltage to mean output voltage. DS20006368A-page 8 2020 Microchip Technology Inc.
