Application Information

Contd

to produce a standard video output

The

VIN of the A side is a buffer output that repro-

duces the input signal and drives RGA and RFA

Into the two resistors 21 mA of error current

flows for a typical 14V of input DC offset creat-

ing distortion in a A-side input stage RGA and

RFA could be increased together in value to re-

duce the error current and distortions but in-

creasing RFA would lower bandwidth A solution

would be to simply attenuate the input signal

magnitude and restore the EL4095 output level

to standard level with another amplifier so
