FUNCTION
1–9
A8, A7, A6,
A5, A4, A3,
A2, A1, A0
Data Bits A8–A0. In dual-port mode, data is directed to the Q-DAC. In single-port mode, data bits
are not used. Connect bits A8–A0 to GND in single-port mode.

GND
Converter 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 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.
Typical Operating Characteristics (continued)
(AVDD3.3 = DVDD3.3 = AVCLK = 3.3V, AVDD1.8 = DVDD1.8 = 1.8V, external reference, VREFIO = 1.25V, RL = 50
double-terminated,
IOUTFS = 20mA, TA = +25°C, unless otherwise noted.)
