Digital system power supply (+5 V)
Digital system ground (0 V)
Channel C negative output. Connect to A.GND through an output resistor R_O (usually 75 Ω).
Channel C positive output. Connect to A.GND through an output resistor R_O (usually 75 Ω).
Analog system power supply (+5 V)
Channel B negative output. Connect to A.GND through an output resistor R_O (usually 75 Ω).
Channel B positive output. Connect to A.GND through an output resistor R_O (usually 75 Ω).
Analog system ground (0 V)
Channel A negative output. Connect to A.GND through an output resistor R_O (usually 75 Ω).
Channel A positive output. Connect to A.GND through an output resistor R_O (usually 75 Ω).
Analog system power supply (+5 V)
Phase compensation capacitor. Connect a 1 µF capacitor between this pin and ground.
Reference current output. Connect a resistor that is 4 times the output resistance R_O to this pin.
Reference voltage input. This input pin sets the analog output dynamic range.
Reference voltage output. The output voltage is set to 0.2 times V_DD by a resistor divider.
When V_DD is 5.0 V, a 1.0 V reference voltage can be acquired from pin 40.
Digital system ground (0 V)
