USING THE AD8067 AT GAINS OF LESS THAN 8
A common technique used to stabilize de-compensated
amplifiers is to increase the noise gain, independent of the
signal gain. The AD8067 can be used in applications where the
signal gain is less than 8, if proper care is taken to ensure that
the noise gain of the amplifier is set to at least the recommended
minimum signal gain of 8 (see Figure 54).
The signal and noise gain equations for a noninverting
amplifier are:

The addition of resistor R2 modifies the noise gain equation.
Note the signal gain equation has not changed.

This technique allows the designer to use the AD8067 in gain
configurations of less than 8. The drawback to this type of
compensation is that the input noise and offset voltages are
also amplified by the value of the noise gain. In addition, the
distortion performance is degraded. To avoid excessive
overshoot and ringing when driving a capacitive load, the
AD8067 should be buffered by a small series resistor; in this
case, a 51 Ω resistor was used.
