Other Parts Discussed in Thread: OPA388
From one of my customers:
"Is there any information available for how the OPA333 input-referred voltage noise varies with temperature? I am interested mainly in the frequency range of 1 to 100Hz. I’ve seen some indications with the OPA333 that there can be noise maxima at certain temperatures in the 20C to 50C range. The amplitude and frequency of these maxima vary from part to part. I suspect the OPA333 vs other parts of the circuit since I can swap the OP333 between circuits and the noise signature vs temperature follows the OPA333."
An additional question to the customer question: Should we be looking at a different amplifier, and if so, which would you recommend?
Thanks
