FSADJUST
Full-Scale Adjust Control. A resistor (RSET) is connected between this pin and AGND to determine the magnitude
of the full-scale DAC current. The relationship between RSET and the full-scale current is as follows:
IOUT FULL SCALE = 18 × FSADJUST/RSET
FSADJUST = 1.14 V nominal, RSET = 6.8 kΩ typical
19
REFOUT
Voltage Reference Output. The AD9838 has an internal 1.20 V reference that is available at this pin.
20
COMP
DAC Bias Pin. This pin is used for decoupling the DAC bias voltage.
EP
Exposed Pad. Connect the exposed pad to ground.
