Passive pull-down resistance is 2 kΩ.
Settling time is specified for a positive-going full-scale step to ± 1/2 LSB. Negative-
The full-scale output voltage is 2.55 V and is guaranteed with a 5 V supply.
A monotonic converter has a maximum differential linearity error of ± 1 LSB.
See Figure 7.
Relative Accuracy is defined as the deviation of the code transition points from the
ideal transfer point on a straight line from the offset to the full scale of the device.
See “Measuring Offset Error” on the AD558 data sheet.
going steps to zero are slower, but can be improved with an external pull-down.
