PULSE RESPONSE
Unlike a traditional voltage feedback amplifier, where the slew
speed is dictated by its front end dc quiescent current and gain
current that increases proportionally to the input step signal
amplitude. This results in slew rates (1300 V/s) comparable
to wideband current feedback designs. This, combined with
relatively low input noise current (2.0 pA/√Hz), gives the
current feedback amplifiers.
LARGE SIGNAL PERFORMANCE
The outstanding large signal operation of the AD9631 and
AD9632 is due to a unique, proprietary design architecture. To
maintain this level of performance, the maximum 550 V × MHz
product must be observed (for example, @ 100 MHz, VOUT ≤
5.5 V p-p).
POWER SUPPLY BYPASSING
Adequate power supply bypassing can be critical when optimiz-
ing the performance of a high frequency circuit. Inductance in
the power supply leads can form resonant circuits that produce
peaking in the amplifier’s response. In addition, if large current
transients must be delivered to the load, then bypass capacitors
(typically greater than 1 F) will be required to provide the best
settling time and lowest distortion. A parallel combination of at
least 4.7 F, and between 0.1 F and 0.01 F, is recommended.
Some brands of electrolytic capacitors will require a small series
damping resistor ≈4.7 for optimum results.
DRIVING CAPACITIVE LOADS
reactive 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 62. Figure 63
shows the optimum value for RSERIES vs. capacitive load. It is
worth noting that the frequency response of the circuit when
driving large capacitive loads will be dominated by the passive
roll-off of RSERIES and CL.
