TERMINAL
I/O
NAME NO.
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.
Compensation and decoupling node, requires a 0.1 µF capacitor to AV DD .
COMP1 19 I
Internal bias node, requires a 0.1 µF decoupling capacitor to AGND.
COMP2 23 I
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 = AV DD ). 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 AV DD 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
Asynchronous hardware power down input. Active High. Internal pulldown. Requires 5 µs to power down but 3 ms
SLEEP 15 I
to power up.

† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
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.
NOTES: 1. Measured with respect to AGND.
2. Measured with respect to DGND.
