DG333ADW-E3

The Vishay DG333ADW-E3 is a precision quad single-pole double-throw (SPDT) analog switch IC. It is designed to control analog signals with a high degree of accuracy, minimizing measurement errors through low on-resistance and low leakage.

Key electrical specifications include a typical on-resistance of 25 Ohms and a maximum of 45 Ohms. The switch offers fast switching times with a typical on-time of 175 ns and off-time of 145 ns. It supports a wide supply voltage range from ±4V to ±22V, with single-supply operation from 5V to 40V. The device features low charge injection (1 pC) and low leakage (0.2 nA).

Fabricated using Vishay Siliconix’s proprietary HVSG-2 CMOS process, this switch ensures higher speed and lower power consumption. An epitaxial layer prevents latch-up, and each switch conducts equally well in both directions when on, blocking voltages up to the power-supply levels when off.

The DG333ADW-E3 is supplied in a 20-SOIC package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C (TA). This component is ideal for applications requiring precise analog signal switching, such as audio switching, test equipment, portable instrumentation, and battery-powered systems.
