Load (speaker) model?

anli · 17th November 2004, 04:39 PM

Can anybody suggest a circuit to emulate an amplifier
8 Ohm speaker/load? I need it for simulating with SPICE.

Thanks!

Thanks!

From the comments above the referenced circuit I see
such circuit must be rather stress load for an amplifier.

I'll try :-)

To estimate "output power" - is it sufficient to use (Uoutput ** 2) / 5.3R ?
I'm mostly interested in 10-20KHz frequencies.

Typically you calculate outputpower for 8ohm, and for sinus-power
you use this formula: Power = Voltswing^2 / (R*2)
