Note 1:
The MCP4802/4812/4822 devices operate over this extended temperature range, but with reduced
performance. Operation in this range must not cause T
J to exceed the maximum junction temperature
of +150°C.
AC CHARACTERISTICS (SPI TIMING SPECIFICATIONS)
Electrical Specifications: Unless otherwise indicated, VDD= 2.7V – 5.5V, TA= -40 to +125°C.
