I'm testing a design in which I need to do a current to voltage conversion. The current ranges from picoamperes to 100mA (both positive and negative), so I use 4 different resistors and a switch to select each of them. I filter the corresponding signal…
Some of the other choices are:
ADA4610-2 if you need a dual
AD8510, and ADA4610-2
All of these are stable at gain of 1 for your voltage follower
When I do a sim on the power supply, you have no attenuation with R20 and C20 until you get past
15 kHz. Try increasing R20 to 100 ohms and C20 to 10 uF. Would also help to put a small ceramic
(0.001-0.01uF) across C20.
The AD8541 is CMOS…
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…
