GND
Ground
11
DVDD3.3
Digital Supply Voltage. Accepts a 3.135V to 3.465V supply voltage range. Bypass with a 0.1F
capacitor to GND.
14, 21, 22, 31,
32
AVDD3.3
Analog Supply Voltage. Accepts a 3.135V to 3.465V supply voltage range. Bypass each pin with
a 0.1F capacitor to GND.
16
REFIO
Reference I/O. Output of the internal 1.2V precision bandgap reference. Bypass with a 1F
capacitor to GND. REFIO can be driven with an external reference source. See Table 1.
17
FSADJ
Full-Scale Adjust Input. This input sets the full-scale output current of the DAC. For a 20mA full-
scale output current, connect a 2k
resistor between FSADJ and DACREF. See Table 1.
18
DACREF
Current-Set Resistor Return Path. Internally connected to GND. Do not use as an external
ground connection.
19, 34
AVDD1.8
Analog Supply Voltage. Accepts a 1.71V to 1.89V supply voltage range. Bypass each pin with a
0.1F capacitor to GND.
24
OUTQN
Complementary Q-DAC Output. Negative terminal for current output.
25
OUTQP
Q-DAC Output. Positive terminal for current output.
28
OUTIN
Complementary I-DAC Output. Negative terminal for current output.
29
OUTIP
I-DAC Output. Positive terminal for current output.
35
AVCLK
Clock Supply Voltage. Accepts a 3.135V to 3.465V supply voltage range. Bypass with a 0.1F
capacitor to GND.
37
CLKN
Complementary Converter Clock Input. Negative input terminal for LVDS/LVPECL-compatible
differential converter clock. Internally biased to AVCLK / 2.
38
CLKP
Converter Clock Input. Positive input terminal for LVDS/LVPECL-compatible differential converter
clock. Internally biased to AVCLK / 2.
39
TORB
Two’s-Complement/Binary Select Input. Set TORB to a CMOS-logic-high level to indicate a two’s-
complement input format. Set TORB to a CMOS-logic-low level to indicate an offset binary input
format. TORB has an internal pulldown resistor.
