Other Parts Discussed in Thread: OPA335
INA333 has relatively CL capacitance - datasheet states CL=500pF.
I've found that using 1n - even with serial resistor of 1k doesn't always lead to stable output. Some parts show oscillations and some not - it's hard to tell.
I've tested several serial resistor values but when some parts were stable with this 1n/1k setup - other were oscillating even with 1n/4k7.
I'd rather not to use such high resistances in my application so the question arises - what distribution of stability I should expect.
The output is at 1,2V at it's max (that's the reference value for AD7706 converter in my application).
For the parts that tend to oscillate at 1n/1k setup, I've tested limiting the CL and I've found that I'd had to go even below 300pF.
That is a bit too much reduction for me (looking at the AD converter requirements).
So my question is - what solution I could use to be sure that my circuit will not oscillate at some combination of input signal/temperature ?
I understand that my 1nF is twice as CL max of 500pF however 1k separation value is quite large resistance I think.
In the INA333 datasheet there is an application with CL exceeding 1nF - together with 10k serial resistor but as I said I'd rather not use such large values (again - ADC specification).
