smd should perform well at these voltages. They also allow the very short tracks that are necessary.
You will put them on the other side from the opamp, directly between the power pins?
Yup, that's what I was thinking of, solder one (10nf?) directly between the pins, but I wonder if I should bypass that with another tank cap, Low ESR FM or something?
Thanks for that, do you think 10nf would be Ok or should I put something bigger in there?richie00boy said:Just use one cap, multiple ones - especially low ESR - can create resonant circuit.
AndrewT said:Hi,
the manufacturer usually gives precise advice on bypassing in the datasheet, including occasional dual cap bypasses, grounded and direct between pins.
that's the thing....No real talk of bypassing just a schematic of the trim feature with 10uf to ground on + & - (not across the pins).
Hi,
the manufacturer's data is usually reliable and often adequate.
An extra pin to pin bypass cap using a small fast ceramic may help attenuate glitches moving into the supply rails and may even be an improvement over doing without.
But, doing other than the recommendation will require a bit of luck and/or extensive testing.
