Description
The CXA1726AM/AS is a multiplier IC which is
used for dynamic convergence, dynamic focus and
others in CRT display monitors and projectors. It is
used in conjunction with an IC (CXA1470AM/AS)
which generates waveforms for deflection
compensation.

Positive supply voltage pin.
Control pin of switch unit.
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.
Input pin of switch unit.

Input Signals
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.
