† 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%/V.
