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.
