Product Summary

The LH2422S is a CRT video driver. It is a wide bandwidth, large signal amplifier designed to swing large voltages of short duration. The LH2422S works on a transimpedanc principle, in that about ±6.5 mA input current results in an output voltage of 土 20V. The primary application for this very fast stewing am­plifier is for driving high resolution monochrome or color graphics monitors. The LH2422S can easily energize a 10 ns pixel. This makes the LH2422S very attractive for 1024 x 1024 displays. The LH2422S is DC coupled and can interface to national LM1201 and LM1203 preamplifiers. Applications are (1)CRT driver for color and monochrome monitors; (2)High voltage transimpedance amplifier.
