Cd4051 Spice — Model Link

If you specifically need a for academic work:

Many engineers host SPICE models on GitHub for public use. cd4051 spice model link

. These can often be used as functional substitutes in simulations if the specific legacy CMOS characteristics (like high voltage rails up to 20V) are not being pushed to their limits. Third-Party Repositories: GitHub projects such as AcheronProject/acheron_ltspice If you specifically need a for academic work:

contains over 20,000 entries and is a reliable backup for finding cross-referenced parts. Implementation Tips CD4051 model - LTspice - Groups.io Ensure your model supports VEEcap V sub cap

It is strongly recommended to verify the model immediately after integration.

: The CD4051 is versatile; it can handle analog signals up to 20VP−P20 cap V sub cap P minus cap P end-sub with dual supplies. Ensure your model supports VEEcap V sub cap E cap E end-sub (negative supply) if you are passing bipolar audio signals. On-Resistance ( RONcap R sub cap O cap N end-sub ) : For precision circuits, remember that RONcap R sub cap O cap N end-sub varies with supply voltage. At , it can be several hundred ohms, while at 15V15 cap V , it drops significantly.
