Note 1 Absolute Maximum Ratings indicate limits beyond which damage to the device may occur
Note 2 Operating Ratings indicate conditions for which the device is functional but do not guarantee specific performance limits For guaranteed specifications
and test conditions see the Electrical Characteristics The guaranteed specifications apply only for the test conditions listed Some performance characteristics
may degrade when the device is not operated under the listed test conditions

Note 10 When measuring video amplifier bandwidth or pulse rise and fall times a double sided full ground plane printed circuit board without socket is
recommended Video amplifier 10 MHz isolation test also requires this printed circuit board
Note 11 Adjust input frequency from 10 kHz (A
Note 12 Measure output levels of the other two undriven amplifiers relative to the driven amplifier to determine channel separation Terminate the undriven
