I have built a voltage amplify circuit with OP297GS.
But sometimes, circuit does not work right, and that will not back to normal.
There is an potentiometer before the Input pin (pin2), but I can't adjust output voltage.
So, I exchange that OP297 with…
The OP297 is the dual version of the OP97 so the OP297.cir model should work. I think the only difference might be that the dual version does not pinout the external compensation pin. If you are using that feature of the OP97 you might have difficulty…
共模电压小于0.1V，现在用OP297和AD708工作正常，就是用AD8639不行。但用AD8639放大反馈信号，工作正常，放大电路形式与此电路完全相同，指示增益较低。反馈信号电压为±1.25V，放大后的输出为±2.1V。

Good day,
I have a task to optimize noise in BW 10Hz - 10kHz.
Voltage gain shall be around 20..50. OA connected directly to source of signal,
which has impedance 1kOm DC and 50Om AC. OA connected to middle point of R1/R2 divider,
where R1 connected…
Chapter 9 Hardware Design Techniques F.pdfHi XY,
let me respond to your questions:
If we use Buffer Mode, Output Additive Jitter is about 140fs. so total rms jitter for AFE ADC clocks should be roots.quare(100*100+140*140+54*54) = 180.3fs rms. Is my perception…
