... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD813 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... Choice of Feedback & Gain Resistors Because current feedback amplifier, the closed-loop band- width of the AD813 depends on the value of the feedback resis- tor. The bandwidth also depends on the supply voltage. In addition, attenuation of the open-loop response when driving load resistors less than about 250 will also affect the band- width ...

... Achieving Low Crosstalk Measured crosstalk from the output of Amplifier 2 to the input of Amplifier 1 of the AD813 is shown in Figure 40. All other crosstalk combinations, (from the output of one amplifier to the input of another), are a few dB better than this due to the addi- tional distance between critical signal nodes. – ...

... S be very fast, typically under 30 ns. When configured for a higher gain, and overloaded at the output, the recovery time will also be short. For example gain of +10, with input overdrive, the recovery time of the AD813 is about 25 ns (see Figure 45). 100 1000 ...

... AD813 High Performance Video Line Driver At a gain of +2, the AD813 makes an excellent driver for a back terminated 75 video line. Low differential gain and phase errors and wide 0.1 dB bandwidth can be realized over a wide range of power supply voltage. Excellent gain and group delay matching are also attainable over the full operating supply volt- age range ...

... Operation Using a Single Supply The AD813 will operate with total supply voltages from 36 V down to 2.4 V. With proper biasing (see Figure 52) it can make an outstanding single supply video amplifier. Since the input and output voltage ranges extend to within the supply rails, it will handle a 1.3 V peak-to-peak signal on a single 3 ...

... Frequency Single Supply Differential Line Driver Due to its outstanding overall performance on low supply volt- ages, the AD813 makes possible exceptional differential trans- mission on very low power. The circuit of Figure 59 will convert a single-ended, ground referenced signal to a differential signal whose common-mode reference is set to one half the supply voltage ...
