AD8616/AD8618
APPLICATIONS
INPUT OVERVOLTAGE PROTECTION
The AD8616/AD8618 have internal protective circuitry that
allows voltages exceeding the supply to be applied at the input.
Rev. A | Page 12 of 16
It is recommended, however, not to apply voltages that exceed
the supplies by more than 1.5 V at either input of the amplifier.
If a higher input voltage is applied, series resistors should be
used to limit the current flowing into the inputs.
The input current should be limited to <5 mA. The extremely
low input bias current allows the use of larger resistors, which
allows the user to apply higher voltages at the inputs. The use of
these resistors adds thermal noise, which contributes to the
overall output voltage noise of the amplifier.
For example, a 10 k resistor has less than 13 nV/√Hz of
thermal noise and less than 10 nV of error voltage at room
temperature.
OUTPUT PHASE REVERSAL
The AD8616/AD8618 are immune to phase inversion, a
phenomenon that occurs when the voltage applied at the input
of the amplifier exceeds the maximum input common mode.
Phase reversal can cause permanent damage to the amplifier
and lock-ups to systems with feedback loops.

DRIVING CAPACITIVE LOADS
Although the AD8616/AD8618 are capable of driving capacitive
loads of up to 500 pF without oscillating, a large amount of
overshoot is present when operating at frequencies above
100 kHz. This is especially true when the amplifier is configured
in positive unity gain (worst case). When such large capacitive
loads are required, the use of external compensation is highly
recommended. This reduces the overshoot and minimizes
ringing, which in turn improves the frequency response of the
AD8616/AD8618. One simple technique for compensation is
the snubber, which consists of a simple RC network. With this
circuit in place, output swing is maintained and the amplifier is
stable at all gains.
Figure 40 shows the implementation of the snubber, which
reduces overshoot by more than 30% and eliminates ringing,
which can cause instability. Using the snubber does not recover
the loss of bandwidth incurred from a heavy capacitive load.
