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.
