Other Parts Discussed in Thread: TINA-TI, , OPA1671
Tool/software: TINA-TI or Spice Models
Hi guys,
My customer found this and wanted to report it to be fixed (not time sensitive, as it is not impeding their progress):
"The OPA1641 Spice model on your web site has problems when the positive power supply (VCC) is too low. Depending on the configuration (inverting, noninverting) you need to apply anywhere from 3.5 to 4 volts on the VCC terminal to make it behave.
BTW, the PSpice model from your web site was dropped in to LTSpice.
Other OPA-type opamp models have worked fine in LTSpice."
Thanks,
Brian
