TDA2003 Spice Model Re-Posted to my Site
I have re-posted the TDA2003 subcircuit, eliminating one of the LIMIT
(*) functions that I suspect is causing LTspice to lock-up on John Woodgate's current-drive amplifier... http://www.analog-innovations.com/TDA2003.zip replacing that function with my smoother TANH approach. Let me know how that plays. If there's still an issue within LTspice, I'll rework the SLEW LIMIT as well. (*) The use of LIMIT dates back to when I didn't know any better :-[ .... all my recent models use TANH for any bounding needs. (LIMIT works in PSpice, but I've grown to distrust it.) ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: skypeanalog | | | Voice480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

Yep. One of the reasons why I never bothered to implement the if-else construct that the uninitiated put into PSpice, and was copied over to LTSpice, in SS. Discontinuous functions and discontinuous derivative functions are an accident waiting to happen. Kevin Aylward www.kevinaylward.co.uk www.anasoft.co.uk - SuperSpice |

The surprise was that LIMIT works in PSpice effortlessly without any OP convergence issues, but throws LTspice into fits where it gives up. However, I _do_ use IF/THEN/ELSE to set parameters that don't change during a simulation run. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: skypeanalog | | | Voice480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.
