Hey Michael, thanks for your interest. I found your composite doc in another thread recently and started reading; I will continue. You know the Groner/Polak composite, right?
Slew rate is not the key factor. This is a pretty unusual application, see below…
Thank you, Zach. You helped me tremendously. Using OPA210 and the user guide you sent can solve most of my problems. If this would not work, I can wait for the OPA928.
However, I have two questions.
1) You mentioned, " The Ib and leakage currents…
Part Number: OPA2210 Other Parts Discussed in Thread: OPA210
Hi,
I need to simulate the stability for OPA2210. I download the TINA model from TI website. And I have done a TINA simulation. But I am not sure CF and RISO value is correct.
OPA2210 input…
Part Number: NE5532 Other Parts Discussed in Thread: OPA210 Hi team,
My customer met a problem using NE5532P, here is the schematic and waveform about the output.
You can see the output has ripple. Do you have any good advice?
GBW goes together with low noise voltage spectral density, and are directly proportional to quiescent current, IQ. Thus, in order to minimize the total noise, you need use an op amp with high GBW (and low noise) BUT limit the bandwidth with an external…
Hi Michael, I’ll check out the OPA210. The ‘noise’ value I am using is the RMS ripple value from the scope. Not as official as what you mention there but is well correlated with audible noise. The 7.5kHz filter cap did make a very audible difference from…

I'm designing a high-precision measurement system that contains a low-noise and high-precision analog OPAMP front-end and an ADC .
