{"product_id":"4-channel-analog-video-distribution-amplifier","title":"4 Channel Analog Video Distribution Amplifier","description":"\u003cp\u003eThis  is a low-cost video distribution amplifier capable of driving up to four video lines. The amplifier is configured with a non-inverting\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003egain of 2\u003c\/strong\u003e. The input video source is terminated in\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e75 Ohms\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eand is applied to the high impedance non-inverting input. Each output line is connected to the op-amp’s output via\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e75 Ohms\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eseries back termination resistor for proper cable termination. The termination resistor at the other end of the lines divides the output signal by 2, which is compensated by the gain of 2 of the op-amp. The project is built using\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eAD8010\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eop-amp which is optimized for this specific function of providing excellent video performance in driving multiple video loads in parallel. Significant power is saved and heat sinking is greatly simplified because of the ability of the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eAD8010\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eto obtain this performance when running on\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e±5 V\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003esupply.
