CLK
Differential Negative LVDS Inputs. Data bits D0–D13 (offset binary format).
Differential Positive LVDS Inputs. Data bits D0–D13 (offset binary format).
No Connection. Leave floating or connect to DGND.
Digital Ground. Ground return for DV
Digital Supply Voltage. Accepts a 3.135V to 3.465V supply voltage range. Bypass with a
0.1µF capacitor to DGND.
Power-Down Input. Set PD high to force the DAC into power-down mode. Set PD low for
normal operation. PD has an internal 2µA pulldown.
No Connection. Leave floating or connect to AGND.
Analog Supply Voltage. Accepts a 3.135V to 3.465V supply voltage range. Bypass with a
0.1µF capacitor to AGND.
Analog Ground. Ground return for AV
Reference I/O. Output of the internal 1.2V precision bandgap reference. Bypass with a
0.1µF capacitor to AGND. REFIO can be driven with an external reference source.
Full-Scale Current Adjustment. Connect an external resistor R
DACREF to set the output full-scale current. The output full-scale current is equal to 32 x
V
Current-Set Resistor Return Path. Internally connected to ground, but do not use as
ground connection.
Analog Supply Voltage. Accepts a 1.71V to 1.89V supply voltage range. Bypass with a
0.1µF capacitor to AGND.
Complementary DAC Output. Negative terminal for current output.
DAC Output. Positive terminal for current output.
Clock Supply Voltage. Accepts a 3.135V to 3.465V supply voltage range. Bypass with a
0.1µF capacitor to CGND.
Clock Supply Ground
Complementary Converter Clock Input. Negative input terminal for differential converter
clock.
Converter Clock Input. Positive input terminal for differential converter clock.
Digital Supply Voltage. Accepts a 1.71V to 1.89V supply voltage range. Bypass with a
0.1µF capacitor to DGND.
Exposed Pad. Must be connected to common point for AGND, DGND, and CGND through
a low-impedance path. EP is internally connected to AGND, DGND, and CGND.
