DG403DY

The Vishay Dale DG403DY is a monolithic analog switch designed for precision high-performance switching of analog signals. It combines low power requirements with high speed, making it suitable for portable and battery-powered applications. This dual SPST switch offers an on-resistance of 45Ω and a fast switching time of 75ns. The device operates within a supply voltage range of ±7V to 22V and supports an analog signal range of ±15V. It features low leakage current and is housed in a 16-SOIC surface mount package. Applications include audio and video switching, sample-and-hold circuits, and test equipment.

The DG403DY is built on a high-voltage silicon-gate process, ensuring high voltage ratings and superior switch performance. It guarantees break-before-make switching action for SPDT configurations. The device prevents latchup due to an epitaxial layer. Each switch conducts equally well in both directions when on and blocks up to 30V peak-to-peak when off. The on-resistance remains very flat over the full analog signal range, comparable to JFET performance without the inherent dynamic range limitations.

Key electrical characteristics include a typical on-resistance of 30Ω, a typical leakage current of 40pA, and a typical power consumption of 0.35µW. The operating temperature range is -40°C to 85°C. The package is a standard 16-SOIC, suitable for surface mounting.
