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.

Typical values are at +25°C.
