Overview
The ADG333ABNZ, 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. This device is fabricated on an enhanced LC2MOS process, which provides a wide analog signal range that extends to the supply rails, low power dissipation, and high switching speeds. The ADG333ABNZ is ideal for applications requiring low on-resistance, low distortion, and fast switching times, making it suitable for use in portable, battery-powered instruments and various signal switching applications.
