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. –8– CXA1726AM/AS Multiplier frequency response [dB] 0 Input X = DC 1V Y = 5Vp-p Sine wave –4 X Y –8 mul.
