    PCB & environmental problems

    HI! I developped an analogic filtering PCB composed by resistor, capacitors (4 of them electrolitics) and operational amplifiers. I have to put it inside an incubator whith 90% humididty, 5% CO2 and temperature 37 °C. Do you know if and how they can affect environment and vicecersa ? Do you have...

    Operational amplifier overloaded

    Hi! I am having trouble with a commercial filtering board made with operational amplifiers; here a part of the documentation: "Due to the low cut-off frequency, the baseline restorer takes some time to stabilize after switching on the amplifier or after replacing the MEA. One to two minutes are...

    Sallen key problem stability

    Hello! I am developping a filtering board for analog signals (bandwidth of interest 300-5khz). I used for this purpose a lowpass Sallen key, a high pass sallen key (all butterworth configuration) and a passive RC low pass for adding a pole. I tried various Gain (3,5 , 5 ,8) on a breadboard and...

    sallen key on breadboard

    Hello! I am releasing on breadboard a high pass filter sallen key + low pass filter SK + passive low pass filter on a breadboard. Acquiring the out signla with labview I had a 3 khz noise that increase too much the gain. Look ak the pics / video. Any idea? On the video I increase the 1 mv input...

    2khz frequency noise

    Hi people ! I am doing some input-referred noise tests on a Pcb. This Pcb is composed by 8 quad-op amp that filter and give gain to signals. Actually I made this test also on his twin boards and I didn't notice frequency noise. Instead in this Pcb there's a big noise at ouptut at 2Khz frequency...

    drill size PCB - EAGLE Cad

    Hello people. I am currently developping a PCB for signal eleaboration with EAGLE software. I used 0.8128mm , 0.4064mm and 0.254mm width wires. I respectively used 0.9 , 0.6 and 0.5 round drills. What do you think about it ? 2) Unfortonately I exchange somo 0.6 with 0.5 drills so there are some...

    [MOVED]Design with Eagle quad-Op-AMp

    Hi people ! I'am new to the world of electronic but i have a work for the university to do : design for 60 channels the following circuit with EAGLE: I want to realize a little board (max 4x3,15 inch) so i was thinking to use a quad-opamp (so : 2 opamp for every channel (as you see from the...
