DRIVING CABLING

DRIVING AN ADC

Because the AD8271 can drive large voltages at high output

currents and slew rates, it makes an excellent cable driver. It is

good practice to put a small value resistor between the AD8271

output and cable, since capacitance in the cable can cause peaking

or instability in the output response. A resistance of 20 Ω or higher

is recommended.

The AD271 high slew rate and drive capability, combined with

its dc accuracy, make it a good ADC driver. The AD8271 can

drive single-ended input ADCs. Many converters require the

output to be buffered with a small value resistor combined with

a high quality ceramic capacitor. See the relevant converter data

sheet for more details.
