NOTES

Tester measures code transitions by dithering the voltage of the analog input (V
). The difference between the measured and the
ideal code width is the DNL error. The INL error is the maximum distance (in LSBs) from the best fit line to any transition voltage
Guaranteed. Not tested.
All channel input pins and ground reference pin have protection which becomes active above
All digital inputs have diodes to V
DD
and AGND. Input DC currents will not exceed specified limits for any input voltage between GND
and V
DD
.
Refin should not vary from Refout by more than
10% of the nominal value of Refout.

NOTES:
1
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a
stress rating only and functional operation at or above this specification is not implied. Exposure to maximum rating
conditions for extended periods may affect device reliability.
Any input pin which can see a value outside the absolute maximum ratings
should be protected by Schottky diode clamps
(HP5082-2835) from input pin to the supplies. All logic inputs have protection diodeswhich will protect the device from
short transients outside the supplies of less than 100mA for less than 100
