AC RESPONSE WITH HIGH VALUE SOURCE AND
FEEDBACK RESISTANCE
Source and feedback resistances greater than 100 kΩ magnify
the effect of the input capacitances (stray and inherent to
the AD549) on the ac behavior of the circuit. The effects of
common-mode and differential input capacitances should be
taken into account because the circuit bandwidth and stability
can be adversely affected.

Figure 33. Follower Pulse Response from 1 MΩ Source Resistance,
Case Bootstrapped
In a follower, the source resistance and input common-mode
capacitance form a pole that limits the bandwidth to πRSCS.
Bootstrapping the metal case by connecting Pin 8 to the output
minimizes capacitance due to the package. Figure 32 and Figure 33
show the follower pulse response from a 1 MΩ source resistance
with and without the package connected to the output. Typical
common-mode input capacitance for the AD549 is 0.8 pF.
In an inverting configuration, the differential input capacitance
forms a pole in the loop transmission of the circuit. This can
create peaking in the ac response and possible instability. A
feedback capacitance can be used to stabilize the circuit. The
inverter pulse response with RF and RS equal to 1 MΩ appears
in Figure 34. Figure 35 shows the response of the same circuit
with a 1 pF feedback capacitance. Typical differential input
capacitance for the AD549 is 1 pF.

COMMON-MODE INPUT VOLTAGE OVERLOAD
The rated common-mode input voltage range of the AD549 is
from 3 V less than the positive supply voltage to 5 V greater than
the negative supply voltage. Exceeding this range degrades the
CMRR of the amplifier. Driving the common-mode voltage above
the positive supply causes the amplifier output to saturate at the
upper limit of the output voltage. Recovery time is typically 2 μs
after the input has been returned to within the normal operating
range. Driving the input common-mode voltage within 1 V of the
negative supply causes phase reversal of the output signal. In this
case, normal operation typically resumes within 0.5 μs of the
input voltage returning within range.
