1-3

DB2-DB0

Data I/O pins. DB0 is LSB.

4V

DD

Positive supply for analog circuitry. This is +15V nominal.

5V

OUT

DAC output voltage pin.

6R

IN

Input to summing resistor of DAC output amplifier. This is used

to select output voltage ranges.

7V

REF-

V

bipolar operation connect it to -5V. The device is specified for

both conditions.

9V

SS

Negative supply for the analog circuitry. This is -15V nominal.

10-19

DB15-DB6

Data I/O pins. DB15 is MSB.

20

DGND

Ground pin for digital circuitry.

21

V

CC

Positive supply for digital circuitry. This is +5V nominal.

22

R/W

R/W Input. This can be used to load data to the DAC or to read

back the DAC latch contents.

23

Chip select input. This selects the device.

24

CLR

Clear Input. The DAC can be cleared to 000...000 or

100...000.

25

LDAC

Asynchronous load input to DAC.

26-28

DB5-DB3

Data I/O pins.
