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 inputs have protection diodes
which will protect the device from short
transients outside the supplies of less than 100mA for less than 100
μ
s.

APPLICATION NOTES
NOTE: When using these DACs to drive remote devices, the accuracy of the output can be improved by utilizing a remote analog
groundconnection. ThedifferencebetweentheDGNDandAGNDshouldbelimitedto
|
300mVtoassurenormaloperation. Ifthere
is any chance that the AGNDto DGNDcan be greater than
|
1 V, we recommend two back-to-backdiodes be used between DGND
andAGNDtoclampthevoltageandpreventdamagetotheDAC. UsingabufferbetweentheremotegroundlocationandAGNDmay
help reduce noise induced from long lead or trace lengths.
