Applications Information (Continued)

Figure 10 shows the LM1201 set up as a video amplifier

with biphase outputs Because the collector of output tran-

sistor Q12 is the only internal connection to VCC3 a75X

termination to the power supply voltage allows one to obtain

inverted video at pin 10 Black level on the non-inverted

video output (pin 8) is set to 15V by the voltage divider on

pin 6

Figure 11 shows how a high frequency video switch may be

designed using multiple LM1201 devices All outputs can

be OR’ed together assuming no more than one channel is

selected at any given time Channel selection is accom-

plished by keeping the appropriate SELECT SWITCH open

Closing the SELECT SWITCH on a given channel disables

that channel’s output (pin 8) leaving it in a high impedance

state A single pair of contrast and brightness potentiome-

ters control the selected channel’s gain and output DC

level
