Yes, when there is no signal and opto and amplifier are disconnected the commom mode output of the opto is about 1,3V (exactly the value said on the datasheet) and when they are connected is almost the same value.
Here is a table with results in both cases, look at the differential voltage how...
Hi, I am trying to make a current transducer with full differential output. It will be used for data acquisition.
The transducer uses a isolation amplifier optocoupler (U1) and a full differential instrumentation amplifier with a integrated ADC driver (IC1).
Everything is OK to the isolation...
SunnySkyguy I was looking for the ESR of my MLCC (part number C3216X6S1E106M) but there is no information about the value on the datasheet, so aI tried to measure it using a 1Khz 1us pulse and a scope described here https://geoffg.net/Measuring_ESR.html and got a 0.05 ohms (don't know if it is...
OK and thanks!!! I just forgot about the ESR on my MLCC :(
I Will try this and the RL filter and PI filter. I am already taking care of EMI using a good ground plane and using a SMA connector with a coax cable to measure the output signal.
In this case, for a RL or PI filter do I need to use...
Hello, we're using TC962 to generate -15V from a +15V positive regulator.
The negative voltage is used to supply 2 general purpose opamp and a differential output amplifier (THS4151).
The TC962 current output is about 23mA.
The problem is that we are observing a little noise coupled ond our...
