Op-amp decoupling - best practice? | diyAudio

OPA134s 'sound' very natural/organic to me, and don't require any decoupling caps to operate well in this circuit. Trying LME49710/20s - a superior op-amp, on paper - and it oscillated. So following DaDa's advice I bypassed from + to ground, and - to ground on one of the op-amps which cured the oscillation hum.

The most important reasons for amplifier IC decoupling are the impedance of the tracks and the noise from the load ( the load is from output to ground and, therefore, through each of the output transistors, from a given power supply rail, the positive or the negative, to ground, fully differential amplifiers are an exception ).

"The essential requirement is that the positive and negative rails should be decoupled with a 100 nF capacitor between them, at a distance of not more than a few millimeters from the op-amp; normally one such capacitor is …

isolation and decoupling, which is often desirable. Possible caveats here would be to verify that the beads never saturate, especially when op amps are driving high output currents. When a ferrite saturates it becomes nonlinear and loses its filtering properties. Note that some ferrites, even before full saturation occurs, can be nonlinear.

How to use Decoupling capacitors for Op amp in dual rail ...
https://forum.allaboutcircuits.com/threads/how-to-use-decoupling-capacitors-for-op-amp-in-dual-rail.20220/
When decoupling op-amps, it is good practice (and design) to use both a small capacitance value (with as short a board trace as you can) as well as a larger bulk capacitance (traces not as critical). These capacitors serve to filter/smooth out/reduce high frequency (small caps) and low frequency (big caps) noise.

Different types of op-amps have very different frequency range: Gain Bandwidth Product (in fact, it typically defines the bandwidth) varies from 1 MHz to 4 GHz, at least. So - decoupling of 4 GHz op-amp by 22 uF capacitors is really weird idea. They have too high impedance in GHz range. They just do nothing for decoupling. Most likely, op-amp would not be stable with such …

Decoupling is a design task worthy of at least the same degree of analysis as calculating an operational amplifier’s gain or filter. Proper decoupling techniques do not have to be any more difficult than other design tasks. It requires the discipline on the part of the designer to take the
