Part Number: OPA2990 Hello TI community, recently I implemented the circuit attached below on a breadboard.
The ratio of attenuation looks good but when I tested the circuit with a sine wave as input the output shows distortion near of the peaks. This…

May I have your kindly suggestion on which product to replace TSX561ILT?
Appreciated for your help here!

Part Number: OPA2990 Hi Team,
Could you please let us know RTME of OPA2990SIDGSR (VSSOP PKG)?
We understand that OPA2990IPWR (TSSOP PKG) has been already released.
However, our customer would like to use VSSOP PKG.
Regards,
Kanemaru
Hi SV,
This ended up taking longer than I intended. For the stability analysis, I had to split the supply rails. I also had to go in and increase the supplies to help the circuit converge.
As you can see here, the phase margin is 32.65 degrees. That…
Part Number: TL032 Other Parts Discussed in Thread: OPA2990 , Hi Dear,
As shown in the following figure, OPA2990 can expand capacitive load driving. If the terminal is a butterfly valve or a PLC or other different equipment, how can users match the R &…
What are the voltages at the inverting inputs (pins 2 and 6) of the amplifiers when the error happens? (I suspect the voltages might be outside the valid common-mode range, i.e., above 13 V. In that case, replacing the LM358 with a rail-to-rail amplifier…
Part Number: OPA4990 Other Parts Discussed in Thread: DAC70502 Hi team,
Currently I want to provide a discrete solution for customers which use DAC70502+OPA2990S/4990S to output both V/I on the same board.
Our AE recommend this circuit for me as below…
This data is published only for the LM358B:
But for both devices, the distribution is centered near zero.
There are known differences in the behaviour of the LM358 and the LM358B, but only if you go outside the valid input common-mode range. So if this…
Hi Adam,
Welcome to E2E! :)
LM358 is not able to swing to the positive supply rail (rail-to-rail output), so you may be seeing some output swing limitation. In our Electrical Characteristics table in the datasheet, we have a specification for output swing…
Part Number: TLV170 Other Parts Discussed in Thread: TLV9002 , OPA2990 Hi,
I want to use a "Bandpass Filter-4th order Butterworth" circuit in audio, connected between the microphone and codec.
Please refer to the attachment for the Simulation…
