Overview
The ADG333A, produced by Analog Devices Inc., is a monolithic complementary metal-oxide semiconductor (CMOS) device that comprises four independently selectable single-pole, double-throw (SPDT) switches. Fabricated on an enhanced LC2MOS process, this device offers low power dissipation, high switching speed, and low on-resistance. It is ideal for applications requiring high linearity and low distortion, such as audio and video signal switching. The ADG333A is suitable for use in portable, battery-powered instruments due to its ultralow power consumption and can operate from a single supply voltage between 3V and 30V or dual supplies up to ±13V and ±20V.
