Hey Marvin,
I'm assuming this is being sensed with an ADC. This introduces a couple limits. First, general purpose amplifiers don't typically go above 40V max supply, so you will at least have to divide the sensor output by more than half to keep it…
Hello user4864313,
The input offset voltage of any op amp will be amplified by the gain used in the circuit. Since the offset voltage is seldom 0 V, but some real amount possibly as high as the maximum value, the output will not be 0 V with zero weight…
Other Parts Discussed in Thread: OPA177 , OPA188 I found there is no low frequency information in closed-loop gain in OPA188 datasheet. Could you provide the information of low frequency in closed-loop gain like as OPA177? Thanks.

Good morning,
I am working with INA 128 for a project and I am actually testing the amplifier responsivity to the signals I will acquire with a temperature…
Hi Francis,
it is a good point that you can save board space with the PGA204. If you can control your switches digitally with your current configuration, you can use that part to save space and use less external components.
The PGA204 uses three op…
Hello Marek Lis,
thanks for the confirmation.
The OPA177 is not an alternative for us, we need the speed of the OPA227.
The OPA227 is a relative old product, I hope, there is a newer device ( bipolar and -15V/+15V supply) with the same or better…
Kevin,
i also think a simple push-pull solution should do the trick. I also came across this solution. In this article, several push-pull solutions for low distortion are highlighted. The last example seems very interesting to me. I tested this with…
Other Parts Discussed in Thread: OPA277 , OPA177 , OP07 Does the OPA277 offer the same gain performance as the OP77? My application requires an amplifier with no or minimal crossover distortion. The OP77 advertised this feature as one of its strengths…
Other Parts Discussed in Thread: OPT101 , OPA177 , REF200 hi,
according to the datasheet of opt101, the dark error may be set with opa177.
Is +/-15V power supply for opa177 only one choice. Will it work with other voltage range?
Or there is other…
