. All voltages referenced to ground (pins 5 and 15) unless otherwise
specified.
Notes
1.
2.
All supply connections must be made to the same external power supply unit.
When the DAC drives a capacitive load above 50 pF, a series resistance of 100
must be used to prevent
oscillations in the output operational amplifier.
