NOTES:
1
Stresses above those listed under “Absolute MaximumRatings” 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 maximumratings 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 fromshort
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 outputcan be improved by utilizing a remote analog
groundconnection. The differencebetweentheDGND andAGNDshouldbelimitedto
|
300mV toassurenormaloperation. Ifthere
is any chance thatthe AGND toDGND canbe greaterthan
|
1 V, we recommendtwoback-to-backdiodes be usedbetweenDGND
andAGND toclampthevoltageandpreventdamagetotheDAC. Using a bufferbetweentheremotegroundlocationandAGND may
help reduce noise induced from long lead or trace lengths.
