ESCRIPTION
Data I/O pins. DB0 is LSB.
Positive supply for analog circuitry. This is +15V nominal.
DAC output voltage pin.
Input to summing resistor of DAC output amplifier. This is used
to select output voltage ranges.
V
REF+
Input. The DAC is specified for V
REF+
= +5V.
V
REF-
Input. For unipolar operation connect V
REF-
to 0V and for
bipolar operation connect it to -5V. The device is specified for
both conditions.
Negative supply for the analog circuitry. This is -15V nominal.
Data I/O pins. DB15 is MSB.
Ground pin for digital circuitry.
Positive supply for digital circuitry. This is +5V nominal.
R/W Input. This can be used to load data to the DAC or to read
back the DAC latch contents.
Chip select input. This selects the device.
Clear Input. The DAC can be cleared to 000...000 or
100...000.
Asynchronous load input to DAC.
Data I/O pins.
