Description of Operation
• Multiplier
The input X and Y signals of the multiplier are multiplied and output to the OUT pins.
• Operational amplifier
This inputs the signals which have been output from the multiplier.
∗ Care is required with ringing in the operational amplifier. Placing a 5p capacitor in parallel with the feedback
resistor is recommended as a preventive measure.
• Switch
The signal input from IN1 is selected for "a" side or "b" side by the SW1 applied voltage.
When SW1 is 2V or less, low turns to "a" side; it is 2.6V or more, high turns to "b" side.
The unselected output pin is connected to GND.
∗ For the multipliers with a switch, "a" side or "b" side is selected under the same conditions.
