Capacitive Load Tolerance
The CBM805X family is optimized for bandwidth and speed, not for driving capacitive loads.
Output capacitance will create a pole in the amplifier’s feedback path, leading to excessive
peaking and potential oscillation. If dealing with load capacitance is a requirement of the
application, the two strategies to consider are (1) using a small resistor in series with the
amplifier’s output and the load capacitance and (2) reducing the bandwidth of the amplifier’s
feedback loop by increasing the overall noise gain. Figure 2. shows a unity gain follower using
the series resistor strategy. The resistor isolates the output from the capacitance and, more
importantly, creates a zero in the feedback path that compensates for the pole created by the
output capacitance.

Figure 2. Indirectly Driving a Capacitive Load Using Isolation Resistor
The bigger the RISO resistor value, the more stable VOUT will be. However, if there is a
resistive load RL in parallel with the capacitive load, a voltage divider (proportional to RISO/RL) is
formed, this will result in a gain error.
The circuit in Figure 3 is an improvement to the one in Figure 2. RF provides the DC accuracy
by feed-forward the VIN to RL. CF and RISO serve to counteract the loss of phase margin by feeding
the high frequency component of the output signal back to the amplifier’s inverting input,
thereby preserving the phase margin in the overall feedback loop. Capacitive drive can be
increased by increasing the value of CF. This in turn will slow down the pulse response.

Typical Application Circuits
Differential amplifier
The differential amplifier allows the subtraction of two input voltages or cancellation of a
signal common the two inputs. It is useful as a computational amplifier in making a differential
to single-end conversion or in rejecting a common mode signal. Figure 4. shown the differential
amplifier using CBM805X.
