Part Number: INA128 Tool/software: for op amps, I keep finding PSRR has two different formulas. I'm having a hard time understanding why the equation is sometimes inverted.
PSRR = 10 log (ΔV supply 2 )/ ΔV io 2 )
and
PSRR=-20 log (ΔV …
Hello,
You can measure the output and then divide by the gain to see what your Vos referred to input is. It is also recommended to match the datasheet test conditions as close as possible if you want to compare to the datasheet specifications.

Part Number: INA128 Good morning Sir
I would like to monitor a floating audio signal (the signal exists on the common part of 2 transformer) Because I want to use only 12VDC single supply, I made the midpoint Vref by using 2 resistors R2 and R3, buffered…
Part Number: INA128 Hello,
INA128UA/2K5, TI datasheet with MSL=3, however, we have received parts and found the label with MSL=2. Please help confirm if MSL=2 for INA128UA/2K5 is normal, is there any PCN document to address the change?
