DC Analog Output Buffer Specifications
The following table lists guaranteed maximum and mini-
mum specifications for the voltage and temperature
ranges, 5V +/- 5% and -40°C <= T_A <= 85°C. Typical
parameters apply to 5V at 25°C and are for design guid-
ance only. For 3.3V operation, see Table 109 on
page 131.
