DESCRIPTION
The CVA1775N includes a cascode CRT driver and a DC bias
cutoff amplifier. All of the active components are inside the
CVA1775N. Only the passive components and protection diodes
are needed to drive a CRT tube. The CVA1775N can easily
drive 70KHz monitors. With the unique feature of DC bias
circuitry the printed circuit board will shrink as EMI performance
will be improved.
