Does anyone have, or know where to find, a model for one of these dual supply, SPDT analog switches?
Where Can I Find a Model for Dual Supply SPDT Analog Switches for Orcard 16.2?
Click For Summary
Discussion Overview
The discussion revolves around the search for a model of dual supply SPDT analog switches suitable for use in Orcard 16.2. Participants explore options for modeling these switches, including potential sources and methods for creating their own models.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant inquires about the availability of a model for dual supply SPDT analog switches.
- Another participant suggests using two voltage-controlled SPST switches from LTSpice to create a SPDT switch.
- Repeated inquiries about the availability of models from Maxim, noting that the "Models" option is greyed out on their website.
- One participant reports that neither Maxim nor Intersil has models available and expresses a need for dynamic input switching at 10kHz.
- A suggestion is made to use simplified schematics from datasheets and add components to model capacitances and other values, which could provide a reasonable starting point for the required frequency.
- A reference to a book titled "Semiconductor Device Modeling with SPICE" is provided as a resource for tuning models.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the availability of models, with multiple views on how to approach the modeling of SPDT switches. The discussion remains unresolved regarding the best method to obtain or create the desired model.
Contextual Notes
Limitations include the lack of available models from major manufacturers and the specific requirements for dynamic switching at a certain frequency, which may affect the applicability of suggested approaches.
