| High Voltage Triple CRT Driver CORPORATION Preliminary Product Information CVA1406T FEATURES DESCRIPTION The CVA1406T contains three high voltage amplifiers with swing range of more than 90Vp-p at 120V supply. It is ideal for DC coupled applications, thus reducing the cost by eliminating DC bias components. It can deliver 12ns video signal, suitable for 14" and 15" applications. The product is housed in the industry standard 11 lead TO-220 molded power package.
