Hi All,
OP97 does not accept a single power supply? I tested it as I-V conversion function as attached.
Connecting 4 pin to -15V power, the OP97 output voltage changes corresponding to amount of light (OP97 works normally), but the output voltage does…
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…
Look at the spec table columns. OP97E and OP97F.
E is lower offset. Get the F for experiments.

我是用AD5543+OP97做恒流源，也遇到类似问题！基准换成AD780也是一样的问题！请帮忙解决下，谢谢！
Mark,
Please see above additional questions,
BTW:
LTC6078 has 25uV maximum offset voltage, as same as OP97
I simulated in SPICE and it should work.
AD8066 cannot be used per your answer above.
I am going…
资料4：运算放大器共模抑制比(CMRR)
I plan to use AD5542A (16 pin TSSOP) in my design. Now I find the pin description on its datasheet is not compatible with the schematic of its evaluation board (ad5542_ug).
Could you verify the pin description of AD5542A?
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…
Hi, Hoagim2013.
A right leg drive amplifier is purposely used for common-mode bias and for noise cancellation especially the 50/60Hz. A high CMRR and and low noise amplifier would suit this application. OP90 and OP193, which Oliver had suggested, are…
