Part Number: OPA378 Other Parts Discussed in Thread: OPA392 , OPA387 , OPA333 So this is following up a bit on this earlier OSI photovoltaic design question. I got to thinking about how to really do this when offset voltage is critical -

Part Number: OPA378 Other Parts Discussed in Thread: REF3125 , OPA625
Hi team,
My customer want to use the reference REF3125 to drive 0-5mA (PWM, 4.8khz), Do we have some recommend circuits and amplifier to support the requirement? if we have the simulation results…
Part Number: OPA378 Other Parts Discussed in Thread: LMP7731 , OPA325 , OPA376 Hi,
I am planning to use OPA378 for interfacing a thermopile that has 68kOhm series resistance. circuit attached. On the non-inverting input, i have the thermopile.
1. Due to…
Other Parts Discussed in Thread: OPA378 , OPA348 Hello,
The OPA378 op amp shows 0 (zero) 1/f or Flicker noise.
Could you please explain why that is?
Thank you, Keith

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…
