The UPC1663G is a video amplifier with differential input and
output stages. A high frequency process (fT = 6 GHz) improves
AC performance compared with industry-standard video amplifiers. This device is excellent as a sense amplifier for highdensity CCDs, as a video or pulse amplifier in high-resolution
displays, and in communications equipment.

Attention:
Due to high frequency characteristics, the physical circuit layout is very
critical. Supply voltage line bypass, double-sided printed-circuit board,
and wide-area ground line layout are necessary for stable operation.
Two signal resistors connected to both inputs and two load resistors
connected to both outputs should be balanced for stable operation.

Since the input impedance of the IC falls when the gain rises, stable operation can
be achieved by inserting a FET buffer when necessary as illustrated above.
