Figure 13. Unity Gain Inverter
In inverting and noninverting applications, the feedback resis-
tance forms a pole with the source resistance and capacitance
(RS and CS) and the OP275’s input capacitance (CIN), as shown
in Figure 14. With RS and RF in the kilohm range, this pole
can create excess phase shift and even oscillation. A small
capacitor, CFB, in parallel and RFB eliminates this problem.
By setting RS (CS + CIN) = RFBCFB, the effect of the feedback
pole is completely removed.

Attention to Source Impedances Minimizes Distortion
Since the OP275 is a very low distortion amplifier, careful atten-
tion should be given to source impedances seen by both inputs.
As with many FET-type amplifiers, the p-channel JFETs in the
OP275’s input stage exhibit a gate-to-source capacitance that var-
ies with the applied input voltage. In an inverting configuration,
the inverting input is held at a virtual ground and, as such, does
not vary with input voltage.Thus, since the gate-to-source voltage
is constant, there is no distortion due to input capacitance modu-
lation. In noninverting applications, however, the gate-to-source
voltage is not constant.The resulting capacitance modulation
can cause distortion above 1 kHz if the input impedance is
greater than 2 kand unbalanced.

Figure 15. Balanced Input Impedance to Minimize
Distortion in Noninverting Amplifier Circuits
Figure 15 shows some guidelines for maximizing the distortion
performance of the OP275 in noninverting applications.The best
way to prevent unwanted distortion is to ensure that the parallel
combination of the feedback and gain setting resistors (RF and
RG) is less than 2 k. Keeping the values of these resistors small
has the added benefits of reducing the thermal noise of the circuit
