Pin Descriptions

PIN NO.

PIN NAME

PIN DESCRIPTION

11, 19, 26

AGND

Analog ground.

13, 24

Analog supply (+2.7V to +3.6V).

28

CLK

Clock Iinput.

27

DGND

Connect to digital ground.

10

Digital supply (+2.7V to +3.6V).

20

FSADJ

Full scale current adjust. Use a resistor to ground to adjust full scale output current. Full scale output

14, 23

NC

Not internally connected. Recommend no connect.

12, 25

ICOMP, QCOMP

Compensation pin for internal bias generation. Each pin should be individually decoupled to AGND with

a 0.1µF capacitor.

1-8, 29-48

ID13-ID0, QD13-QD0 Digital data input ports. Bit 13 is most significant bit (MSB) and bit 0 is the least significant bit (LSB).

15, 22

IOUTA, QOUTA

Current outputs of the device. Full scale output current is achieved when all input bits are set to binary 1.

16, 21

IOUTB, QOUTB

Complementary current outputs of the device. Full scale output current is achieved on the complementary

outputs when all input bits are set to binary 0.

17

REFIO

Reference voltage input if Internal reference is disabled. The internal reference is not intended to drive an

external load. Use 0.1µF cap to ground when internal reference is enabled.

18

REFLO

9

SLEEP
