Hi Alexander,
I understand the time-dependent dielectric breakdown measurement. Only thing I don't get is why 1.2kVrms is put as the maximum working voltage. Is there no reason for it? 76 years is not a requirement, then spec could've been 1.1kV or 1…
Part Number: ISO124 Other Parts Discussed in Thread: ISO224 , AMC1411 , AMC3330 I need to take a continuous voltage measurement of approximately 60-260VDC, pass it across an isolation boundary of at least 1500V, and then create an analog representation…
Hi Cesar,
Unfortunately the ISO124 is an older device so access to design documentation is limited and I'm not entirely sure what inside the ISO124 would cause this behavior. Most likely a chopper either on the output. I do notice however, that all of…
Hi Spyros,
The ISO122 is nearly 30 years old now! You can find our policy on part longevity at this link . If you are interested, please take a look at the ISO224 which is a newer device that has a similar input voltage range to the ISO122 but uses a smaller…
Hi Paul,
No, I'm sorry but this will not work. The ISO124 needs two bipolar supplies for the input and output stages and those need to be 4.5V minimum. The -Vsx cannot be tied to ground. If this is a new design and you need the wider spacing provided…
Hi Upasana,
To use the ISO122, you would have to have at least +/-5V power supplies on each side of the device - you need the negative rail as well as the positive. If you can limit the input voltage to 0-2V, you might consider the AMC1411. The AMC1411…
Hi Cynthia,
I wasn't able to find any equivalent parts in Cross reference tool. Thank you for letting me know a new part, AMC1411.
Q1. Could you also let me know when it would be released?
In addition, customer is using SI8932B-IS, a single ended…
Hi Dino,
The AMC1311 is specified for operation from -0.1V to 2V as you showed in the datasheet. Sensing a bipolar voltage range within the 0-2V input range would require additional front end circuitry as discussed in this thread: https://e2e.ti.com/support…
