TDA9201 WIDE BAND VIDEO PREAMPLIFIER PRELIMINARY DATA ■ ■ ■ ■ ■ ■ ■ ■ ■ CURRENT OUTPUT (up to 300mA) 120MHz (-3dB) BANDWIDTH 3nsec RISE/FALL TIME BRIGHTNESS AND CONTRAST DC CONTROLLED INTERNAL CLAMPING PULSE GENERATOR CONTRAST PRE-ADJUST FOR COLOR MONITOR APPLICATION INTERNAL REFERENCE VOLTAGE GENERATOR BLANKING PULSE INPUT POS/NEG SYNC POLARITY INPUT DESCRIPTION The TDA9201 is a wide band video amplifier intended for high resolution monochrome or color monitors. The BRIGHTNESS and CONTRAST are DC controlled. The brightness loop includes a comparator gated by an internally generated pulse. Thanks to the contrast pre-adjust pin, this device is well suited for color application too. The output stage structure (A class current output), allows to use a very cheap high voltage amplifier using only one transistor.
