Video Gain Control Fader Multiplexer

Application Information Contd

The A channel gains the input by a1 and the B

channel by b1 Feedthrough suppression of the

Y input can be optimized by introducing an off-

set between channel A and B This is easily done

by injecting an adjustable current into the sum-

ming junction (bVIN terminal) of the B input

channel

The two input channels can be connected to a

common input through two dissimilar filters to

create a DC-controlled variable filter This circuit

provides a controlled range of peaking through

rolloff characteristics
