Clear Input (active low). Driving this asynchronous input low sets the content of all latches to
1000hex. All DAC outputs are reset to AGND_.
Analog Ground for DAC C and DAC D
Reference Voltage Input for DAC C and DAC D. Bypass to AGNDCD with a 0.1µF to 1µF capacitor.
Negative Power Supply, -5V (2 pins). Connect both pins to the supply voltage. Bypass each pin
to the system analog ground with a 0.1µF to 1µF capacitor.

DAC A Output Voltage
Positive Power Supply, 5V (2 pins). Connect both pins to the supply voltage. Bypass each pin to
the system analog ground with a 0.1µF to 1µF capacitor.
Reference Voltage Input for DAC A and DAC B. Bypass to AGNDAB with a 0.1µF to 1µF capacitor.
Analog Ground for DAC A and DAC B
Load Input (active low). Driving this asynchronous input low transfers the contents of input latches
A and B to the respective DAC latches.
