VIDEO LINE DRIVER
The AD847 functions very well as a low cost, high speed line
driver for either terminated or unterminated cables. Figure 23
shows the AD847 driving a doubly terminated cable in a fol-
lower configuration.
The termination resistor, RT, (when equal to the cable’s charac-
teristic impedance) minimizes reflections from the far end of the
cable. While operating from
±5 V supplies, the AD847 main-
tains a typical slew rate of 200 V/
s, which means it can drive a
±1 V, 30 MHz signal into a terminated cable.

*–3 dB bandwidth numbers are for the 0 dBm signal input. Overshoot numbers
are the percent overshoot of the 1 volt step input.
A back-termination resistor (RBT, also equal to the characteristic
impedance of the cable) may be placed between the AD847 out-
put and the cable input, in order to damp any reflected signals
caused by a mismatch between RT and the cable’s characteristic
impedance. This will result in a flatter frequency response, al-
though this requires that the op amp supply
±2 V to the output
in order to achieve a
±1 V swing at resistor R
T.
Figure 24 shows the AD847 driving 100 pF and 1000 pF loads.

FLASH ADC INPUT BUFFER
The 35 MHz unity gain bandwidth of the AD847 makes it an
excellent choice for buffering the input of high speed flash A/D
converters, such as the AD9048.
Figure 25 shows the AD847 as a unity inverter for the input to
the AD9048.
