Part Number: OPA227 Other Parts Discussed in Thread: OPA189 Hi all
My customer has a non-inverting amplifier with a gain=10 with the OPA227 and he asks about the long-term drift of the output voltage.
What value can they expect ?
... and would you…
Part Number: OPA227 Hi, I need a suptitude for a discontinued HA17741 opamp. I believe OPA227 would work (the HA17741 work at lower temperature than the standard 741 opamp). If this one is not 100% compatible, do you have a better match?
Thank you!
Part Number: REF102 Other Parts Discussed in Thread: OPA227 , , OPA277 Dear member of this forum,
I need to generate a very precise 10 uA current .
I used the schematic in the description of the REF102 chip together with the OPA227 Op Amp.

The purpose of our system is to measure a 80VAC signal generated by an independent power supply (Totally different ground) , and convert it into…
Hi Rajesh,
The OPA227 requires a minimum supply voltage difference of 5V. This means that you can indeed use this part with a single +5V supply and V- shorted to GND. However, you must be aware of the common mode input limitations of the OpAmp. The…
Part Number: OPA227 Hi Team, My customer is evaluating offset voltage of OPA227 under thermostat bath. He said offset voltage is slightly different (~0.5uV) between before and after ambient temperature cycling. (20°C -> 90°C -> 20°C) Is it possible case…
Hello Laxmi kant
The OPA227 is not a rail to rail output opamp
Hence the maximum output swing on a +5V and 0 V supply is only 2V min to 3V max
I would recommend using a rail to rail opamp to get the output swing from 0V - 5 V
Please refer…
