Video amplifier circuit: TDA6107

TDA6107 has three independent video amplification circuits built-in, with dark current detection function. It can input not only the three primary color signals of R, G, and B, but also the three primary color color difference signals of RY, BY, GY, and Y. The picture shows the input of R, Application diagram for G and B primary color signals.

Pin 1: 2.3V——R (or RY) signal input

Pin 2: 2.3V——G (or GY) signal input

Pin 3: 2.3V——B (or BY) signal input

Pin 4: 0V - ground

Pin 5: 6.7V - AC ground (or Y signal input)

Pin 6: 195V - power supply

Pin 7: 140V——B signal output

Pin 8: 140V——G signal output

Pin 9: 140V——R signal output
