STV9555 9.5 ns TRIPLE-CHANNEL HIGH VOLTAGE VIDEO AMPLIFIER FEATURES s s s s s s s s s s s Triple-channel video amplifier Supply voltage up to 115 V 80V Output dynamic range Perfect for PICTURE BOOST application requiring high video amplitude Pinning for easy PCB layout Supports DC coupling (optimum cost saving) and AC coupling applications. Built-in Voltage Gain: 20 (Typ.) Rise and Fall Times: 9.5 ns (Typ.) Bandwidth: 37 MHz (Typ.) Very low stand-by power consumption Perfectly matched with the STV921x preamplifiers above is required, ensuring a maximum quality of the still pictures or moving video. Perfecly matched with the STV921x ST preamplifiers, it provides a highly performant and very cost effective video system. DESCRIPTION The STV9555 is a triple-channel video amplifier designed in a 120V-high voltage technology and able to drive in DC-coupling mode the 3 cathodes of a CRT monitor. The STV9555 supports PICTURE BOOST applications where video amplitude up to 50V or CLIPWATT 11 (Plastic Package) ORDER CODE: STV9555 PIN CONNECTIONS 11 10 9 8 7 6 5 4 3 2 1 OUT1 OUT2 OUT3 GNDP VDD GNDS GNDA IN3 VCC IN2 IN1 Version 4.0 September 2003 1/24 1 Table of Contents 1 2 3 4 5 6 BLOCK DIAGRAM . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 PIN DESCRIPTION . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 ABSOLUTE MAXIMUM RATINGS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 THERMAL DATA . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 ELECTRICAL CHARACTERISTICS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 THEORY OF OPERATION . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 6.1 6.2 7 8 9 General . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 Output voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 POWER DISSIPATION . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 TYPICAL PERFORMANCE CHARACTERISTICS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 INTERNAL SCHEMATICS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11 10 APPLICATION HINTS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 10.1 10.2 10.3 10.4 10.5 10.6 10.7 10.8 10.9 How to choose the high supply voltage value (VDD) in DC coupling mode . . . . . . . . . 12 Arcing Protection: schematics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 .
