CVA1775N

CRT Driver + DC Bias Amplifier CORPORATION Preliminary Data Sheet CVA1775N FEATURES 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.
