com DESCRIPTION The GB4551 is a high performance video buffer with DC restore primarily used for accurate back porch clamping.
The circuit features a wideband differential amplifier that can be configured as a gain stage.
The output signal voltage is limited to +2V above the clamp level in order to prevent damage to crosspoints or other circuits connected to the output.
The clamping action occurs when the STROBE (STB) input is take...
