Description

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

Voltage Reference Output. The AD9838 has an internal 1.20 V reference that is available at this pin.

DAC Bias Pin. This pin is used for decoupling the DAC bias voltage.

Exposed Pad. Connect the exposed pad to ground.
