LM386 Spice model

I got this one from somewhere , can't remember where. Can't vouch for its accuracy.. , seems to be ok.

*lm386 subcircuit model follows:

• IC pins: 2 3 7 1 8 5 6 4

• | | | | | | | | ..subckt lm386 inn inp byp g1 g8 out vs gnd

• input emitter-follower buffers:

q1 gnd inn 10011 ddpnp r1 inn gnd 50k q2 gnd inp 10012 ddpnp r2 inp gnd 50k

• differential input stage, gain-setting

• resistors, and internal feedback resistor:

q3 10013 10011 10008 ddpnp q4 10014 10012 g1 ddpnp r3 vs byp 15k r4 byp 10008 15k r5 10008 g8 150 r6 g8 g1 1.35k r7 g1 out 15k

• input stage current mirror:

q5 10013 10013 gnd ddnpn q6 10014 10013 gnd ddnpn

• voltage gain stage & rolloff cap:

q7 10017 10014 gnd ddnpn c1 10014 10017 15pf

• current mirror source for gain stage:

i1 10002 vs dc 5m q8 10004 10002 vs ddpnp q9 10002 10002 vs ddpnp

• Sziklai-connected push-pull output stage:

q10 10018 10017 out ddpnp q11 10004 10004 10009 ddnpn 100 q12 10009 10009 10017 ddnpn 100 q13 vs 10004 out ddnpn 100 q14 out 10018 gnd ddnpn 100

• generic transistor models generated

• with MicroSim's PARTs utility, using

• default parameters except Bf:

..model ddnpn NPN(Is=10f Xti=3 Eg=1.11 Vaf=100

• Bf=400 Ise=0 Ne=1.5 Ikf=0 Nk=.5 Xtb=1.5 Var=100

• Br=1 Isc=0 Nc=2 Ikr=0 Rc=0 Cjc=2p Mjc=.3333

• Vjc=.75 Fc=.5 Cje=5p Mje=.3333 Vje=.75 Tr=10n

• Tf=1n Itf=1 Xtf=0 Vtf=10)

..model ddpnp PNP(Is=10f Xti=3 Eg=1.11 Vaf=100

• Bf=200 Ise=0 Ne=1.5 Ikf=0 Nk=.5 Xtb=1.5 Var=100

• Br=1 Isc=0 Nc=2 Ikr=0 Rc=0 Cjc=2p Mjc=.3333

• Vjc=.75 Fc=.5 Cje=5p Mje=.3333 Vje=.75 Tr=10n

• Tf=1n Itf=1 Xtf=0 Vtf=10)

..ends
