Other Parts Discussed in Thread: OPA177 , OPA27 , OPA277 Iam using Op-amp opa177 for the samll signal amplification purpose. In op-amp opa177 pin no.1 & 8 are used for offset trim. but if I do not want to trim the offset So where should I connect these…
Hi Dogan,
Yes, the scope shots indicates the switching frequency is not properly attenuated by the LC low pass filter, where I see 200kHz to 500kHz switching frequency in your DC supply rails. The op amp's PSRR does not attenuate such high frequency…
Part Number: LMC7215 Other Parts Discussed in Thread: OPA177 , TLC393 Tool/software: Hello,
I recently came across an informative post on EDN discussing how to test operational amplifier characteristics. However, I've encountered difficulties when attempting…
Part Number: INA101 Other Parts Discussed in Thread: OPA177 , Hello,
I'm using two INA101HP (DIP package) stages in series.
The signal from a sensor (~100Ohms) as input for the Amplifier is 0-500uV AC with a DC-offset in the range of 0-120mV. The…
Part Number: OPA2205 Other Parts Discussed in Thread: OPA277 , OPA177 Tool/software: The OPA2205 has a really nice, low maximum offset voltage of 25uV across temperature, compared to 55uV for the OPAx205A. Will it come out anytime soon, or do you have…
Part Number: UA741 Other Parts Discussed in Thread: TLE2021 , TL071 , OPA277 , OPA177 , TL031 Tool/software: Hello, we have bought a bunch of op-amps UA741CP from Mouser distributor and tried to use them in one of our typical data acquisition and control…
The OPA177 datasheet says:
Burr-Brown’s standard ESD test method consists of five 1000V positive and negative discharges (100pF in series with 1.5kΩ) applied to each pin.
This corresponds to the HBM test conditions.
Hi Manoj,
this might interest you:
Take the TI's OPA177 for this circuit or better.
You should decide whether you take a thin film or silicon based sensor. They greatly differ in their temperature coefficients.

Part Number: OPA2277 Other Parts Discussed in Thread: OPA177 Dears,
My customer use OPA2277 to detect AC input voltage as below circuit. The input signal is AC(50Hz) 0.2V pk voltage. But customer found big output voltage spike when input signal zero…
We designed this circuit to build a PGA circuit. The block diagram is as follows.
The default state switch (RF Switch) of the board design is not connected to the previous stage. It is equivalent to the following figure. All tests are tested in the…
