  • RE: TINA/Spice/OPA838: PSpice OrCAD Capture Model for OPA838

    JC Zhu

    Hi Ryan, How did you "load" the model when you say "PSpice can't load them all"? To use the file OPA838.LIB, you need to do 2 things: Create a libary (an OLB file) so that you can place a symbol in your schematic. This is done by the cadence model…

    I had meant to also mention there is a background project to update these models to what is call the GWL template - again a macromodel but much more methodical on these kinds of issues - perhaps that is nearing completion for the OPA838 model and it will…

    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…

  • RE: OPA838: Unexpected Large Offset Voltage

    Hi Pengkun, input bias current of OPA838 is typically 1.5µA.This will cause a voltage drop of 4.5mV across R31 (3k). This voltage drop is amplified by the noise gain of your circuit ((R32+R33)/R32=8) and appears as 36mV offset voltage at output of…
