The AD8174 offers 3 dB signal AD8174-EB evaluation board bandwidth of 250 MHz and a slew rate greater than 1000 V/s. The AD8174 has excellent video specifications with low EQUIPMENT NEEDED differential gain of 0.02%, low differential phase error of 0.05, Signal source or video pattern generator and signal analyzer and 0.1 dB flatness out to 85 MHz. With a low 78 dB at 5 MHz Power supplies (+2 V/1 A and 5 V/1 A) of crosstalk and better than 88 dB at 5 MHz isolation, the SMA to BNC cables for inputs, outputs, and other pins AD8174 is useful in many high speed applications. It is also a low power device consuming only 9.7 mA from a 5 V supply. The AD8174 offers a high speed disable feature that allows the user to put the output into a high impedance state for cascading stages so that the off channels do not load the output bus. In addition, the AD8174 can be shut down when not in use to minimize power consumption (IS = 1.5 mA). The AD8174 is available in 14-lead PDIP and 14-lead SOIC packages. Full details about the device are available in the AD8174 data sheet, which should be consulted when using the AD8174-EB.
