ZXFV4089 VIDEO AMPLIFIER WITH DC RESTORATION DEVICE DESCRIPTION The ZXFV4089 is a DC restoring circuit and low-distortion video amplifier. It is specially designed to provide brightness level stability as a ‘black-level clamp’ in video systems with very low distortion and low power consumption. A high fidelity video amplifier is combined with a sample-hold switch circuit using an external coupling capacitor to provide level-shifting of the video output such that a time-gated sample of the waveform is set to be equal to an external reference voltage (usually zero voltage). A buffered TTL/CMOS logic input signal controls the switch. The gain is set externally by two resistors.
