Part Number: AMC1300 Other Parts Discussed in Thread: ISO120 , ISO121 , ISO224 , Hello,
I'm designing a high voltage(DC/AC) sensing circuit of signals that go up to 50kHz, However after doing simulation on TINA TI, it seems there starts to be a phase delay…
Part Number: ISO124 Other Parts Discussed in Thread: ISO120 , ISO121 Hello,
I have a few questions iso124U.
1. I would like to know if the ISO124U is of bipolar technology only or CMOS or TTL?
2. Has the ISO124 been used before for any aerospace application…
Lance,
There isn't a simulation model for the ISO124, but there is one for the ISO120. It is an older model that wasn't developed for Orcad, but instead for MicroSim PSpice. However, Orcad is based on the original MicroSim PSpice and the model should…
Hello Madhumita,
There are a couple of obsolete and NRND isolation amplifiers that have PSpice (.MOD) simulation models available via the TI website; ISO120 and ISO130. The ISO120 is more similar to the ISO124 than the ISO130 - so you may want to give the …
Part Number: ISO121 Other Parts Discussed in Thread: ISO120 This is Takeuchi, D-CLEW Technologies, Thank you for your help. Please help me regarding ISO121 SPICE Model downloaded from TI website. Using ISO121 or 124,We expect that minus DC output control…
Other Parts Discussed in Thread: ISO124 , ISO120 , DCV011515D , DCP011515DB I'm designing an 8 channel interface board with +/- 10V inputs using ISO124U isolation amplifiers. I would like to use 2 +/- 12Vdc isolated DC/DC converters to power all 8 ISO124Us…
Fatin,
If you could provide more detail on your measurement problem we may be able to provide better advice.
What is the frequency range of your signal of interest? 100kHz is the upper limit. What is the low end of the frequency range of interest?
…
Bruce,
I wrote up the whole circuit and ran it by the project lead. He's adamant about everything on the high voltage side being completely isolated from the low voltage monitor; the high-common mode differential amplifiers are not sufficient.

Part Number: ISO121 Other Parts Discussed in Thread: AMC1300 , AMC1301 Hi,
My applicaiton is to measure a current-source (200nA to 10uA) of 50ohm, and the Isolation is to be 3KV and above. I have selected ISO121 as an Isolation Amplifier for the rated 5KVdc…
