DESCRIPTION

The CVA24150T is a single channel, very high voltage
amplifier, designed to drive a CRT. It is capable of delivering
65MHz at 100V
excellent linearity. Emitter peaking option is available to
adjust the high frequency response. CVA24150T features
high gain to match existing pre-am plifier drive cap ability.

APPLICATION INFORMATION

The CVA24150T is a very high voltage amplifier. Using standard
Cascode topology, it is designed primarily to meet the
requirement of High Definition Television (HDTV), Projection
Television, arcade displays, etc. CVA24150T can deliver
100V

yet require only 180V supply voltage. CVA24150T

P-P

frequency resplonse is excellent, can energize 20ns pixels at
100V

into 10pf. At 40pf load, rise time is 18ns.

P-P

CVA24150T has very high gain (~34) to match any of the
available pre-amplifiers. An emitter peaking option is also
provided to adjust the high frequen cy respo nse.

The product is housed in industry standard 11 lead TO-220
power package.

Thermal Considerati ons

The transfer characteristics of the amplifier are shown in

Figure 3.
