Abstract :
Introduces an A/D video interface circuit which represents an important advance in the integration of functions for digital video signal processing. The IC includes an 8-orbit A to D converter (ADC), and input selector and a high-performance video amplifier with clamp level adjustment and automatic gain control (AGC). A DAC is not necessary for these control functions because they are performed digitally by the ADC outputs via three simple digital comparators in a time-controlled loop.<>
