  ISO224: Vdd2 split supply

  TI Thinks Resolved

  Part Number: ISO224 Hi, my ADC has an input range of +-4V with Vcm at 0V, which I cant change. Now I has to monitor a +-400V potential rail. Yes +- 400V, the polarity changes. Is it possible to supply the ISO 224 with +-2.5V (as my ADC is supplied...

  RE: ISO224: ISO224BDWVR

  Hi Alice, This looks good, I wasn't aware that you had capability for a 2-layer board. That is correct, however if you look at the GND connections to the terminal blocks, you will see that 4 traces connect to the GND pad of the terminal block. Since...

  RE: WEBENCH® Tools/ISO224: AC voltage sensing without any DC power supply using ISO224

  Hi Varun, Referencing the first schematic in your original post: 1. Capacitor C3 is unnecessary, short this out as the negative of C2 should still be connected to GND1. 2. May want to increase the size of C2 in order to provide a more stable voltage...

  RE: ISO224: Power supply for isolated amplifier

  Hi Fausto, As Kai said, the modulator frequency is 20MHz. The clock used transfer the data across the isolation is 480MHz. General rule of thumb is to set the cutoff frequency of the anti-aliasing filter at least one decade below the modulator frequency...
