Clamp voltage output pin
A capacitor of at least 1 F should be connected between this pin
and the V
Should be left open if the clamp circuit is not used.
Analog signal input pin
Analog reference voltage pin
In the DIP model, this pin is internally connected to the reference
circuit.
Always be sure that a capacitor is connected immediately next to the
IC, between this pin and the ground. The capacitor must be at least
1 F with excellent frequency characteristics.
Reference voltage monitor pin
Set to the midpoint of resistance between V
Should be left open in normal use.
Reference voltage output pin
Should be left open when no reference voltage source is used.
Analog reference voltage input pin
When an internal reference voltage source is used, this pin should
be shorted to the V
capacitor is connected immediately next to the IC, between this pin
and the ground. The capacitor must be at least 1 F with excellent
frequency characteristics.
When an external reference voltage source is used, this pin will
carry a current of up to 8.5 mA, therefore it is necessary to use a
voltage source with sufficient sync capacity.
A capacitor connection should also be used similar to that used with
internal reference voltage sources.
