SPICE Models - Linear Amplifiers
The Apex Precision Power library of SPICE models for linear and PWM amplifiers are readable by a wide variety of SPICE simulators. These SPICE models are provided below for download, or you can request the entire library on CD-ROM. The APEXLINEAR.ZIP file contains APEXLINEAR.LIB (a text file with most Apex Precision Power SPICE models for linear amplifiers) plus APEXLINEARPSPICE.ZIP and APEXLINEARBERKELEY.ZIP. These last two zip files contain text files for some models requiring different syntax for the two simulator types. The INTUSOFTSYMBOLS file is a .zip archive that contains a partial set of symbol files unique to Intusoft. TOPSPICESYMBOLS is a complete set of symbols for TopSPICE.
- Apex Linear (ZIP, 127 KB) - Updated 6/18/2010 with new MP103 models
- Intusoft Symbols (ZIP, 9 KB)
- TopSPICE Symbols (ZIP, 4 KB)
SPICE Models - PWM Amplifiers
The Apex Precision Power library of PWM SPICE models are state average models for nine amplifiers. With no switching, these models run about one hundred times faster than the pulse-by-pulse macro models. These SPICE models are provided below for download, or you can request the entire library on CD-ROM. APEXPWM.ZIP is a .zip archive that contains apexpwm.txt, a versatile generic PWM Spice model. For details on how to use this model, see Apex Applications Note 33 “Spice Model and PWM Amplifier Applications.”
