• Manufacturer: ELANTEC [Elantec Semiconductor]

Application Information
Here the A input channel is configured for a gain
of
its input attenuated by
tuous because the distortions do not increase
monotonically with reducing gain as would the

For video levels however these constants can
give fairly high differential gain error The prob-
lem occurs for large inputs Assume that a
‘‘twice-size’’ video input occurs The A-side stage
sees the full amplitude but the gain would be set
to 100% B-input gain to yield an overall gain of
