LH2426 Datasheet | National Semiconductor

Description The LH2426 contains three wide bandwidth large signal amplifiers designed for large voltage swings at high frequencies The amplifiers work on a transimpedance principal i e an input current swing of g 4 38 m A results in an output voltage swing of g 25V The device is intended for use in color CRT monitors and is a low cost solution to designs .. conforming to the IBM 8514 graphics standard Features Y Y Y Y Y Operation from 80V power supply 80 MHz bandwidth at 50 VPP swings Rise fall time less than 4 ns Output signal can swing 70V Drives CRT directly Applications CRT driver for RGB monitors High voltage transimpedance amplifiers Schematic and Connection Diagrams (One Section) TL H 10739 - 2 Top View Order Number LH2426S See NS Package Number HY12B TL H 10739 - 1 IBM is a registered trademark of International Business Machines Corporation C1995 National Semiconductor Corporation TL H 10739 RRD-B30M115 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 V a Power Dissipation PD a 85V Storage Temperature Range TSTG Operating Temperature Range TCASE Lead Temperature (Soldering 10 sec ) ESD Tolerance b 25 C to a 100 C b 20 C to a 90 C 10W 300 C TBD DC Electrical Characteristics V a e 80V R1 e 430X C1 e 82 p F CL e 8 p F 50 VPP output swing with 40V DC offset See Figure 1 TCASE e 25 C unless otherwise noted Symbol Va V Parameter Supply Current (per Amplifier) Input Offset Voltage Output Offset Voltage Rise Time Fall Time Bandwidth Voltage Gain Overshoot Linearity Error Gain Matching VOUT from a 10V to a 70V Note 1 Note 2 10% to 90% 90% to 10% b 3 d B Conditions Min No Input or Output Load 14 34 LH2426 Typical 24 16 40 35 35 100 11 13 10 5 02 14 Max 30 18 46 5 5 Units m A V V ns ns MHz V V % % d B INDC ..
