Hi Taito,
OPA2376 is trimmed means that its input offset voltage and drift is adjusted in the package by blowing resistor links.
Grade out means that in the final test the parts are sorted out by parametric limits. For example, parts with |Vos|<25uV go…
Just in case you wonder why in unipolar case Kai picked R7/R8 of 24k/1k, it is to reference the lower-end of the output voltage range around 500mV above ground to assure OPA180 linear operation as specified in the AOL conditions - see below.
Doing so…
Hi Qin,
Sorry for the late response but I have reviewed the schematic you sent with the original questions and have the following feedback below.
The question regarding the current source, it is a good current source design that provides plenty of flexibility…
Hi Chitransh,
there's no need for a Monte Carlo simulation in TINA-TI as you can easily perform a parameter sweep as explained here:

With +/-1% toleranced resistors…
Hi Asaishi-san,
There is a small difference between the OPA2180 and the OPA180/4180 that results in different input bias specs. However, any of the devices from this family (any channel count and package) operates up to 125C.
Part Number: TL082 Other Parts Discussed in Thread: OPA180 , TL052 Hi team,
Customer want to know the time drift of TL082, I did not find it in the datasheet.
I found OPA180 datasheet it has long term stability spec.
Part Number: OPA2180 Other Parts Discussed in Thread: OPA180 , OPA4180 , Hi Team,
Good day,
We received a query from customer and they want to understand more about the open-loop gain vs temperature of the said device. For me to not miss any information,…
Part Number: OPA192 Other Parts Discussed in Thread: OPA180 , As far as I know, the ideal open-loop output impedance of an op amp should be as low as possible.
But I see the open-loop output impedance of opa192 is really high especially at low frequency…
Hi Pier,
I made a TINA simulation circuit according to your schematic, see attached file. OPA180 is used because it has TINA model and similar bandwidth as TL072. If the jack is unplugged , this amplifier circuit will output a signal close to zero (27…
