Digital Power Supply pins (+ 5 V).
Analog Power Supply pins (+ 5 V).
Digital Ground (0 V). These pins should be connected to the
analog ground on the application system.
Analog Ground (0 V). These pins should be connected to the
analog ground on the application system.
ADC Digital Output pins. TTL level.
ADC Clock Input pin. TTL level.
ADC Reference Voltage Input pin. (5 V Input)
Sync Tip Clamp Circuit Analog Input pin. (0 - 3 V, 1.95 V
When a clamp circuit is not used, this pin is connected to
ground.
Clamp Circuit Analog Output pin. It is used by adding a
capacitor (1 F or more) between V
When a clamp circuit is not used, this pin is left open.
Clamp Voltage Output pin (3.05V Output). When a clamp
circuit is not used, this pin is left open.
ADC Analog Signal Input pin. (3 - 5 V)
ADC Middle Reference Voltage Monitor pin. (Mid of V
is set to this pin). Normally this pin is left open.
ADC Reference Voltage Input pin. (3 V)
Reference Voltage Output pin. (Resistor Divider, 3 V)
By connecting this pin to V
When a reference voltage is not used, this pin is left open.
DAC Reference Voltage Input pin (3 V)
Phase Compensation Capacitor pin. (Capacitor greater than
0.1 F should be connected between this pin and Analog
Ground.)
Analog Signal Output pin
DAC Clock Input pin. TTL level.
DAC Digital Data Input pins. TTL level.
