NOTES

1 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.

2Passive pull-down resistance is 2 k

Ω.

3Settling time is specified for a positive-going full-scale step to

±1/2 LSB. Negative-

going steps to zero are slower, but can be improved with an external pull-down.

4The full-scale output voltage is 2.55 V and is guaranteed with a 5 V supply.

5A monotonic converter has a maximum differential linearity error of

±1 LSB.

6See Figure 7.

Specifications shown in boldface are tested on all production units at electrical test.

Specifications subject to change without notice.

*Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. This is a stress rating only; functional operation of the

device at these or any other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect device reliability.
