Web6 mar 2016 · This is shown in Figure 24 in the datasheet, which plots phase margin vs. capacitive load for G = +1 and -1 configurations (reposted here for convenience). In a gain of -1 the OPA1622 has 54 degrees of phase margin with a 1nF capacitive load and no series isolation resistor. I'm not a big fan of overshoot vs cap load graphs.
