... Furthermore the AD810 is specified over a power supply range The AD810 works well as an ADC or DAC buffer in video systems due to its unity gain bandwidth of 80 MHz. Because the AD810 is a transimpedance amplifier, this bandwidth can be maintained over a wide range of gains while featuring a low noise of 2 ...

... GENERAL DESIGN CONSIDERATIONS The AD810 is a current feedback amplifier optimized for use in high performance video and data acquisition systems. Since it uses a current feedback architecture, its closed-loop bandwidth depends on the value of the feedback resistor. Table I below contains recommended resistor values for some useful closed- loop gains and supply voltages ...

... Gain = + DISABLE MODE R = 750 F By pulling the voltage on Pin 8 to common (0 V), the AD810 can be put into a disabled state. In this condition, the supply current drops to less than 2.8 mA, the output becomes a high impedance, and there is a high level of isolation from input to output ...

... OPERATION AS A VIDEO LINE DRIVER The AD810 is designed to offer outstanding performance at closed-loop gains of one or greater gain of 2, the AD810 makes an excellent video line driver. The low differential gain and phase errors and wide –0.1 dB bandwidth are nearly independent of supply voltage and load (as seen in Figures 49 and 50) ...

... AD810 2:1 VIDEO MULTIPLEXER The outputs of two AD810s can be wired together to form a 2:1 mux without degrading the flatness of the gain response. Figure 54 shows a recommended configuration which results in –0.1 dB bandwidth of 20 MHz and OFF channel isolation MHz supplies. The time to switch between channels is about 0 ...
Page 15
... N:1 MULTIPLEXER A multiplexer of arbitrary size can be formed by combining the desired number of AD810s together with the appropriate selection logic. The schematic in Figure 58 shows a recommendation for a 4:1 mux which may be useful for driving a high impedance such as the input to a video A/D converter (such as the AD773). The output series resistors effectively ...
