LM1203 Datasheet | National Semiconductor

Description The LM1203 is a wideband video amplifier system intended for high resolution RGB color monitor applications In addition to three matched video amplifiers the LM1203 contains three gated differential input black level clamp parators for brightness control and three matched attenuator circuits for contrast control Each video amplifier contains a gain set or ‘‘Drive’’ node for setting maximum system gain (Av e 4 to 10) as well as providing trim capability The LM1203 also contains a voltage reference for the video inputs For high resolution monochrome monitor applications see the LM1201 Video Amplifier System datasheet Features Y Y b 3d B) Three wideband video amplifiers (70 MHz Inherently matched ( g 0 1 d B or 1 2%) attenuators for contrast control Three externally gated parators for brightness control Provisions for independent gain control (Drive) of each video amplifier Video input voltage reference Low impedance output driver Block and Connection Diagram TL H 9178 - 1 FIGURE 1 Order Number LM1203N See NS Package Number NA28F C1996 National Semiconductor Corporation TL H 9178 RRD-B30M56 Printed in U S A Absolute Maximum Ratings If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Supply Voltage VCC Pins 1 13 23 28 (Note 1) 13 5V Voltage at Any Input Pin VIN VCC t VIN t GND Video Output Current I16 20 or 25 28 m A 2 5W Power Dissipation PD (Above 25 C) Derate Based on i JA and TJ Thermal Resistance i JA 50 C W Junction Temperature TJ 150 C Storage Temperature Range TSTG Lead Temperature (Soldering 10 sec ) b 65 C to a 150 C 265 C ESD susceptibility 1 k V Human body model 100 p F discharged through a 1 5 k X resistor Operating Ratings (Note 9) Temperature Range Supply Voltage (VCC) 0 C to 70 C 10 8V s VCC s 13 2V Electrical Characteristics See Test Circuit (Figure 2) DC Static Tests S17 Label Is V11 Parameter Supply Current Video Input...
