A comparison between the EasyEDA LM386 improved spice model and the "NO-FRILLS LM386 MODEL" by Dave Dilatush 5/30/95.

The EasyEDA LM386EE/NJM386EE spice subcircuit model is a new model developed for EasyEDA by

The LM386EE subcircuit is featured in the Tesseract Guitar Practice Amplifier simulation files:

To copy the subckt netlist, open the schematic in the editor and do:

Super Menu > Miscellaneous > Netlist for Document > Spice...

or simply download a copy of the LM386EE.sub.txt attachment.

The subckt is based on the schematic shown in the NJM386 datasheet:

Specifications are based on the above and:

The EasyEDA spice subcircuit offers improved modelling of output voltage self-centring, typical quiescent and input bias currents and unloaded bandwidth.

Output swing is optimistic with < 8 Ohm load resistances although the reason for this is unclear.

To help improve the model in this area, if anyone is willing to share scope traces of the LM386 output voltage driving into clipping with loads of between 4 - 16 Ohms, please contact:
