Part Number: ISO121 Hi,
We are planning to use ISO121 for one of our application.
There are cases in which, we will apply the input signal (0-5VDC) to this iso amp Vin pin without applying the power supplies to its +/-Vs1 and +/-Vs2 pins. Will this condition…
Part Number: ISO121 Other Parts Discussed in Thread: ISO122 , ISO124 We have selected ISO121 amplifier for our analog signal isolation. But have a feeling that the amplifier is just not the right fit for our application.
Our application has input voltage…
Hi Samuel,
Can you be more specific about the 'something' that is hooked up into the input? With the input floating, I'm not suprised that the output tends to go to the rails. With +/-9V, you would have about +/-7V output max. from the ISO121.…
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…
Hi,
Can I connect the -VS1 to GND1 and connect +VS1 to 15V1 supply (referenced to the same GND1)? My input signal range is between 6V-12V.
The isolated side will have +15V2 at +VS2, -15V2 at -VS2, and GND2 and GND.
Regards,
Syed Akhtar
Hi Jigar,
10mV with respect to 5V is 0.2% which AMC3330 can achieve.
The AMC1311B offers additional increase in accuracy:
Indeed, there is a stock shortage throughout much of the semiconductor industry. It looks like the only devices we currently have…
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 , ISO224 , ISO121 Hi TI Support,
I am using ISO124 in our current project, I would like to run PSPICE simulation but there was no model for it. I saw ISO120 has a model, perhaps I can use it as…
Hi Alessandro!
Welcome to our e2e forum! I'm curious to know what your application is here - we have a new isolation amplifier (the ISO224) which might be better suited for your work. I don't have an input impedance readily available for the ISO121…
Part Number: ISO122 Other Parts Discussed in Thread: ISO224 , , ISO121 , AMC1301 , AMC1200 , AMC1100 Hi, all.
In datasheet of ISO 122 stated that it rated at 1500Vrms. Can i use it in 2kV isolation circuitry as shown as figure below?
