Hi,
Just got interested in the OPA1656.

Any advice on how to get the spice model from TI to work with Micro-Cap?

Got a new design going. I was always using other chips for power. Finally, this time is opa1656. Extreme power, +-24V operation, extreme low distortion.

5.5W at 32ohm and 870mW at 300ohm single ended is pretty extreme ei? As THX calls 3.9W at 32ohm extreme.
