Cd4051 Spice Model |top| File

When a channel is off, there is still a small leakage current (nA to µA) that can affect high-impedance circuits. This is critical for sample-and-hold or low-power sensor interfaces.

provide ECAD models, though these are often footprint/symbol-focused rather than behavioral SPICE models. 2. Anatomy of the Model: Behavioral vs. Structural Most CD4051 SPICE models are subcircuits ). They generally include: Logic Level Shifters: The CD4051 can handle analog signals up to 20 cap V sub cap P minus cap P end-sub while being controlled by cd4051 spice model

Third, there is and feedthrough . Even when a channel is "off," parasitic capacitance (e.g., source-to-drain capacitance) allows a fraction of the input signal to leak to the output. A high-frequency analog signal can thus appear on the output even on a deselected channel. When a channel is off, there is still
