    Capacitor going to input of op-amp ruining ramp rate

    Hi all, I have this IC which creates a linear voltage ramp proportional to the input voltage based on the capacitor on the output in parallel to ground. I then have to do some analog computation using op amps. When I connect the output of this IC to an op-amp, the ramp is ruined. Is there any...

    Frequency meter with MAX22707 - short circuit between digital GND and Neutral

    Hi all, I'm currently designing a low-cost domestic AC frequency meter. I decided to use Analog Device's MAX22707 (datasheet) precision zero crossing detector IC after obtaining promising results in the first stage of prototyping. Then, I designed a custom PCB which I'm currently testing...
