Analog_video_switch_and_amplifier_with_ac_coupled_input
This circuit shows a CA3256 switch/amplifier connected for an ac coupled input. One of four channels can be selected in parallel with channel 5. The analog switches of channels 1 to 4 are digitally controlled by logic (Fig. 3-35B).Vcc can be from + 12 to + 18 V.VEE is grounded, Amplifier gain is determined by external resistor Rf, as shown by the equation. A typical value of CCOMP is 6 pF.
