NOTES:

Specifications are subject to change without notice

VOUT must be less than VDD by 3.5 V to ensure correct operation.

Total Unadjusted Error includes zero code error, relative accuracy and full-scale error.

Calculated after zero code error has been adjusted out.

Sample tested at 25

°C to ensure compliance.

The glitch impulse transferred to the output of one converter (not adjusted) due to a change in the digital input code to another

addressed converter.

All input rise and fall times are measured from 10% to 90% of +5 V, tR = tF = 5 ns.

Timing measurement reference level is (VINH + VINL)/2.

NOTES:

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 inputs have protection diodes which will protect the device from short

transients outside the supplies of less than 100mA for less than 100

µs.
