Miscellaneous

ƒ

Double buffered output latches

ƒ

Update DACs individually or simultaneously (jumper selectable by pairs)

ƒ

Power up and reset option, jumper selectable (revision 3 and up): With

jumper set to "ZERO", all DAC's cleared to 0 volts, ±32 mV, DACs set to
simultaneous update mode until first read. With jumper set to "STD", DAC
output on power-up is undefined.
