REV. A
of the disable the disable pin for 5 V supplies. If driven by
complementary output CMOS logic (such as the 74HC04), the
disable time (until the output goes high impedance) is about
100 ns and the enable time (to low impedance output) is about
170 ns on 5 V supplies. The enable time can be extended to
about 750 ns by using open drain logic such as the 74HC05.
When operated on 15 V supplies, the AD810 disable pin may
be driven by open drain logic such as the 74C906. In this case,
adding a 10 k pull-up resistor from the disable pin to the plus
supply will decrease the enable time to about 150 ns. If there is
a nonzero voltage present on the amplifier's output at the time it
is switched to the disabled state, some additional decay time will
be required for the output voltage to relax to zero. The total
time for the output to go to zero will generally be about 250 ns
and is somewhat dependent on the load impedance.
OPERATION AS A VIDEO LINE DRIVER
The AD810 is designed to offer outstanding performance at
closed-loop gains of one or greater. At a 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).
