Sony CXA1726AS, CXA1726AM Datasheet
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.

Description
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.
