LM1201 Video Amplifier System
January 1995
LM1201 Video Amplifier System
General Description
The LM1201 is a wideband video amplifier system intended for high resolution monochrome or RGB monitor applications In addition to the wideband video amplifier the LM1201 contains a gated differential input black level clamp comparator for brightness control and an attenuator circuit for contrast control The LM1201 also contains a voltage reference for the video input For medium resolution RGB color monitor applications also see the LM1203 Video AmF plifier System data sheet

FIGURE 2 LM1201 AC DC Test Circuit
Note When V5 s 0 8V and S9 is closed DC feedback around the Video Amplifier is provided by the clamp comparator Under these conditions sine wave or 50% duty cycle square waves can be used for test purposes The low frequency dominant pole is determined by C2 at Pin 2 Capacitor C9 at pin 9 prevents overloading the clamp comparator inverting input See applications section for additional information T

FIGURE 3 Typical Application of the LM1201
30X resistor is added to the input pin for protection against current surges coming from the 10 mF input capacitor By increasing this resistor to well over 100X the rise and fall times of the LM1201 can be increased for EMI considerations h
