Hello again Art,
Thank you for your reply. I'd like to ask a few more questions.
How to add gain resistor to OPA378s. Is it need to placed between negative inputs of OPA378s or two seperate resistor need to use like standard gain circuit?
Do I…

Part Number: OPA348 Other Parts Discussed in Thread: OPA378 Hello
I am struggling with a few things designing a double stage Sallen-Key LPF and between PSpice and real circuit there are up to +/- 1 dB of variation at 10 kHz.
The circuit is:

Hi Roberto,
Thanks for your inputs. Sorry, I forgot to mention that we have changed the gain to limit the current to 40A on individual converter. The output of the OPA378 is also as per calculations.
As of now, everything is fine expect a small hissing…

...oh also let me know if there is a better TI opamp to use in the inverting opamp configuration. I'm not married to the OPA191. I like the OPA378 but my rails are +3.3V and -3V and it can't handle that wide of a supply range. The opamp needs low offset…
Hi Vincenzo,
Thank you for your post, I can help you. What is the required bandwidth? As you know, we want to look for a low-power amplifier to not exceed the threshold that would cause the light bulb to illuminate. Here are a few of our low-power amplifiers…
Other Parts Discussed in Thread: OPA378 , OPA316 I have a laser driver current clamp circuit utilizing the OPA378. During DVT testing I discovered this part suffers from an increased input bias current (increases into the uA range) when the input differential…
Hi Future,
Since you have not provided detailed product design requirements, I will provide you some ideas. This is based on the information you provided so far. The following suggestion is one of the design options.
1. Please take a look at OPA378…
