TABLE 1. 7846 PINOUT DESCRIPTION

SYMBOL

DESCRIPTION

DB2-DB0

Data I/O pins. DB0 is LSB.

VDD

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

VOUT

DAC output voltage pin.

RIN

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

to select output voltage ranges.

VREF+

VREF-

VREF+ Input. The DAC is specified for VREF+ = +5V.

VREF- Input. For unipolar operation connect VREF- to 0V and for

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

both conditions.

VSS

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

DB15-DB6

Data I/O pins. DB15 is MSB.

DGND

Ground pin for digital circuitry.

VCC

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

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

back the DAC latch contents.

CS

Chip select input. This selects the device.

CLR

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

100...000.

LDAC

Asynchronous load input to DAC.

DB5-DB3

Data I/O pins.
