Hi;
I am currently seeking a pre-configured model for the OP847 that works on ORCAD Pspice. Previously I had no issue with any TI models however, this particular model has some instruction that is not clear on how to revise the model.
I much rather an expert from TI revise the model so that it can be imported into ORCAD.
Pasted in this text box is the first lines of the model instructions.
Please advise accordingly.
Thanks
*OPA847 Wideband, Ultra-Low Noise Voltage Feedback Operational Amplifier with Shutdown
* REV. A - Created 7/14/06 X-ramus2@ti.com
*
*
* NOTES:
* 1- This macromodel predicts well: DC, small-signal AC, noise,
* , and transient performance under a wide range
* of conditions.
* 2- This macromodel does not predict well: distortion
* (harmonic, intermod, diff. gain & phase, ...),
* temperature effects, board parasitics, differences
* between package styles, and process changes
* 3- For Spice3F4 users they might need to un-comment the lines for the F
* function and comment out the Lines for PSpice F functions
* and subckts. First try the present netlist then comment out lines if
* errors appear.
* General form:
* FXXXXXXX N+ N- <POLY(ND)> VN1 <VN2 ...> P0 <P1 ...> <IC=...>
* Examples:
* F1 12 10 VCC 1MA 1.3M
* 4- For some simulators the subckt for the F statement need to be placed
* inside the ends statement followed by carriage return
* 5- Known Problems: - None
