QA460 Capacitive Load

Can the QA460 drive into highly capacitive loads without oscillating?

It’s generally not an issue. There will be some overshoot, of course, but generally no ringing. Below is a plot of the QA460 driving 500 mVpp (measured at QA460 output port which has 20 dB atten) 100 kHz into 2x4700uF = 9400 uF caps = dead short at 100 kHz . The power opamp used in the QA460 is an OPA564, which is well behaved under a host of reactive loads.

This plot is 500mVp into QA460, which is 5Vp out of QA460 into 0.1uF.

Awesome performance!
