  • AMC1311: AMC1311BQDWVRQ1

    TI Thinks Resolved
    Part Number: AMC1311 Other Parts Discussed in Thread: TIDA-01541 , , OPA211 Dear all, I am using AMC1311B isolation amplifier for DC link voltage sensing in motor drive application. At No load to motor, DC link measurement is linear to actual values…

  • RE: OPA2191: Cross regulation issue with OPA192 in 3-phase 400V measurement using shared neutral point

    Hi Rock, Rock Shao said: When enabling only one phase (e.g., L1 = 494V, others = 0V), the output is stable (e.g., ~7.8630V). This implies that the difference amplifier is attenuated at 7.8630/495.83 = 0.015858 V/V. or 39k/(3*820k) in attenuation.…

  • RE: INA240: High common mode voltage. 230V

    Resolved
    Hi Luuk, The INA138 floating circuit will not work well as an inline current sensor, because it is unidirectional. There are circuit examples in the datasheet for bidirectional current sensing. You might be able to adapt them similarly into floating…
