  • TINA/Spice/OPA348: OPA348

    Part Number: OPA348 Other Parts Discussed in Thread: TINA-TI Tool/software: TINA-TI or Spice Models Hello, I dont think I am getting the right output when I try to induce an offset.Please see the file attached. The offset seems to be 2V instead of 1V. …

  • OPA348-Q1: how to estimate Gain Error for Shunt Amplifier application ?

    TI Thinks Resolved
    Part Number: OPA348-Q1 Hi Team using OPAMP, I would like to make Shunt Amplifier to measure a current. the output will be affected by DC Offset and Offset Drift over temperature and Gain error. I can estimate worst case of DC Offset and Offset Drift…

  • RE: OPA348 1/f or Flicker Noise

    Keith, OPA348 clearly shows the 1/f input voltage noise  spectral density - see Fig 17 datasheet; it is 35nV/rt-Hz @ 1kHz and 650nV/rt-Hz @ 1Hz.  There is, however, no 1/f input current noise that is typical in CMOS op amps.

  • [OPA348-Q1] what is the Abs Mas voltage for the differential input voltage ?

    Other Parts Discussed in Thread: OPA2348 , OPA4348-Q1 , OPA348 Hi Team inOPA348-Q1(OPA2348/OPA4348-Q1) datasheet, there is no comment on the Abs Mas voltage for the differential input voltage. may i know it ?

  • RE: TLV2371: Zero_crossing detection of current

    Mohammed, Who is the person who put U5B TLV4376 in the current zero and U2 OPA348 in the voltage zero? These two circuits make zero crossing harder to detect. They are completely unnecessary for zero cross. Can these two circuits be removed or the zero…
