Notes
1.
2.
All supply connections must be made to the same external power supply unit.
At 3 V supply voltage, the input pads are TTL compatible. However, at 2.0 V supply voltage no TTL levels can be
accepted, but levels from 3.3 V domain can be applied to the pins.
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.
