The macromodel published in the TLV245x family (SLOS218F, December 1998 - Revised January 2005) seems to have a magnitude error in the component Rp (shunting between nodes 3 and 4: VCC and Ground). The downloaded file, has Rp with the same error: its value is given as 147.06 ohms, which would make this something other than a micropower op amp. Few users probably model the power pins in PSpice, but my feedback loop is a floating negative power rail, created by a resistor in series with analog ground. How much current is dumped into this resistor (virtual/floating ground) raises or lowers the supply of the op amp, so I need accurate modeling of this resistor between VCC and Ground, nodes 3 and 4. The TLV2764 model--similar in many ways to the op amp I am modeling--has Rp in kilo ohms; I assume the correct magnitude for Rp in the TLV245x should be in kohms also. That would give a much more reasonable supply current number for the TLV245x model. Can anyone from TI confirm this--that the 147.06 number in the macro model should be 147.06e+03?
