Operating current assumes all inputs are tied to either VSS or VDD with no input currents due to programmed pullup resistors. The DAC output
and other outputs are open circuited.
The frequency of the internal clock has a temperature coefficient of approximately – 0.2 % /
°C and a VDD coefficient of approximately ±1.4%/V.
