  • AMC1303E2520: Comparing performance

    TI Thinks Resolved
    Part Number: AMC1303E2520 Hello, Looking at the AMC1303 family of devices, there is a 250mV and a 50mV version.Performance wise I don't really see much of a difference. Is there anything else that sets the two apart from each other?

    Resolved
    MarkoAnte, Can you please clarify if my understanding is correct? 1) 3-phase voltage measurement uses AMC1303E2520 modulator: - 50Hz signal - No problem with SDFM results 2) DC voltage measurement uses AMC1303E2520 modulator: - No problem with SDFM…

    So I have tired and replaced 1 AMC1306E25 with 1 AMC1303E2520 . Everything else the same. It works fine. Could it really be bad chips?

    Hi Marko, Take a look at the AMC1303E2510 or AMC1303E2520, there are also 50 mV input versions of this device.

  • RE: AMC1306E25: Synchronisation of insulated sigma delta ADC

    Hi Marko, I meant a clock buffer that drives 2-4 devices, you would not necessarily have to drive each line independently. There is no substantial gain using the DSP clock, an external oscillator is fine - or the AMC1303 option you mentioned earlier…
