DRIVING CAPACITIVE LOADS
If driving loads with a capacitive component is desired, the best
frequency response is obtained by the addition of a small series
resistance, as shown in Figure 53. Figure 54 shows the optimum
value for RSERIES vs. capacitive load. The test was performed with
a 50 MHz, 50% duty cycle pulse, with an amplitude of 200 mV p-p.
The criteria for RSERIES selection was based on maintaining
approximately 1 dB of peaking in small signal frequency
response. It is worth noting that the frequency response of the
circuit can be dominated by the passive roll-off of RSERIES and CL.

POWER DOWN PIN
The ADA4860-1 is equipped with a power-down function.
The POWER DOWN pin allows the user to reduce the quiescent
supply current when the amplifier is not being used. The
power-down threshold levels are derived from the voltage
applied to the VS pin. When used in single-supply applications,
this is especially useful with conventional logic levels. The
amplifier is powered down when the voltage applied to the
POWER DOWN pin is greater than (VS + 0.5 V). The
amplifier is enabled whenever the POWER DOWN pin is left
open, or the voltage on the POWER DOWN pin is less than
(VS + 0.5 V). If the POWER DOWN pin is not used, it should
be connected to the negative supply.
VIDEO AMPLIFIER
With low differential gain and phase errors and wide 0.1 dB
flatness, the ADA4860-1 is an ideal solution for consumer and
professional video applications. Figure 55 shows a typical video
driver set for a noninverting gain of +2, where RF = RG = 499 Ω.
The video amplifier input is terminated into a shunt 75 Ω resistor.
At the output, the amplifier has a series 75 Ω resistor for
impedance matching to the video load.

SINGLE-SUPPLY OPERATION
Single-supply operation can present certain challenges for the
designer. For a detailed explanation on op amp single-supply
