Pin Descriptions

PIN NO.

PIN NAME

PIN DESCRIPTION

1-8

D7 (MSB) Through Digital Data Bit 7 (Most Significant Bit) through Digital Data Bit 0, (Least Significant Bit).

D0 (LSB)

9-14

DCOM

Connect to digital ground.

15

SLEEP

Control Pin for Power-Down mode. Sleep Mode is active high; Connect to ground for Normal Mode. Sleep

pin has internal 20A active pulldown current.

16

REFLO

Connect to analog ground to enable internal 1.2V reference or connect to AVDD to disable internal

reference.

17

REFIO

Reference voltage input if internal reference is disabled. Reference voltage output if internal reference is

enabled. Use 0.1F cap to ground when internal reference is enabled.

18

FSADJ

Full Scale Current Adjust. Use a resistor to ground to adjust full scale output current. Full Scale Output

Current = 32 x VFSADJ/RSET.

19

COMP1

For use in reducing bandwidth/noise. Recommended: connect 0.1F to AVDD.

20

ACOM

Analog Ground.

21

IOUTB

The complimentary current output of the device. Full scale output current is achieved when all input bits

are set to binary 0.

22

IOUTA

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

23

NC

Internally connected to ACOM via a resistor. Recommend leave disconnected. Adding a capacitor to

ACOM for upward compatibility is valid. Grounding to ACOM is valid. (For upward compatibility to 12-bit

and 14-bit devices, pin 23 needs the ability to have a 0.1F capacitor to ACOM.)

24

AVDD

Analog Supply (+3V to +5V).

25

NC

No Connect (for upward compatibility to 12 and 14b, pin 25 needs to be grounded to ACOM).

26

DCOM

Digital Ground.

27

DVDD

Digital Supply (+3V to +5V).

28

CLK

Input for clock. Positive edge of clock latches data.
