transition for all input bits. This time is typically 70 ns for
settling to within LSB for 8-bit accuracy. This time applies
when R

and settles in 65 ns. In applications where the DAC

when measuring settling time. Short leads, 100 mF supply
bypassing for low frequencies, minimum scope lead
length, and avoidance of ground loops are all mandatory.
