AGND 20 I Analog ground return for the internal analog circuitry
AV
DD
24 I Positive analog supply voltage (3 V to 5.5 V)
BIASJ 18 O Full-scale output current bias
CLK 28 I External clock input. Input data latched on rising edge of the clock.
COMP1 19 I Compensation and decoupling node, requires a 0.1 µF capacitor to AVDD.
COMP2 23 I Internal bias node, requires a 0.1 µF decoupling capacitor to AGND.
D[7:0] [1:8] I Data bits 0 through 7.
D7 is most significant data bit (MSB), D0 is least significant data bit (LSB).
DGND 26 I Digital ground return for the internal digital logic circuitry
DV
DD
27 I Positive digital supply voltage (3 V to 5.5 V)
EXTIO 17 I/O Used as external reference input when internal reference is disabled (i.e., EXTLO = AVDD). Used as internal
reference output when EXTLO = AGND, requires a 0.1 µF decoupling capacitor to AGND when used as reference
output
EXTLO 16 O Internal reference ground. Connect to A VDD to disable the internal reference source
IOUT1 22 O DAC current output. Full scale when all input bits are set 1
IOUT2 21 O Complementary DAC current output. Full scale when all input bits are 0
MODE 25 I Mode select. Internal pulldown. Mode 0 is selected if this pin is left floating or connected to DGND. See
timing diagram.
NC [9:14] N No connection
SLEEP 15 I Asynchronous hardware power down input. Active High. Internal pulldown. Requires 5 µs to power down but 3 ms
to power up.

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
