  • OPA838: OPA838

    TI Thinks Resolved
    Part Number: OPA838 Hello everyone, I am trying to simulate the OPA838 in LT-SPICE. I had followed the procedure described here: https://e2e.ti.com/support/tools/simulation-hardware-system-design-tools-group/sim-hw-system-design/f/simulation-hardware…

  • RE: OPA838: RF – Small Signal Low Noise Amplification and Demodulation

    Thanks for the insight and orientation Kai. I have gone through and removed all of the filters, which required some pretty fancy soldering of jumpers for the 0603 capacitors... I have to pat myself on the back for that :).. I would say my overall assessment…

  • TINA/Spice/OPA838: The OPA838 TINA spice model has occurred floating error for using some standard SPICE.

    TI Thinks Resolved
    Part Number: OPA838 Other Parts Discussed in Thread: TINA-TI Tool/software: TINA-TI or Spice Models I tried to use the OPA838 with LTspice :-P, however the TINA SPICE model has occrred a floating error at GRA and GRC node. I have solved this error to modify…

  • OPA838: Operating Voltage

    TI Thinks Resolved
    Part Number: OPA838 Other Parts Discussed in Thread: OPA354 What is the maximum dual supply rating for the part? It appears to be 5.5v/2=2.75v so the part cannot be operated with anything greater than +2.75v to -2.75v. Is this true? I was hoping to operate…
