GENERAL DESCRIPTION
The XRD5408/10/12 are low power, voltage output
digital-to-analog converters (DAC) for +3V power supply
operation. The parts draw only 70mA of quiescent current
and are available in both an 8-lead PDIP and SOIC
package.
The XRD5408/10/12 have a 3 wire serial port with an
output allowing the user to daisy chain several of them
together. The serial port will support both Microwiret,
SPIt, and QSPIt standards.
The outputs of the XRD5408/10/12 are set at a gain of +2.
The output short circuit current is 7mA typical.

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.
2 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 100ms.
