Description

The ADG333A is a monolithic complementary metal-oxidesemiconductor (CMOS) device comprising four independentlyselectable single-pole, double-throw (SPDT) switches. It isdesigned on a linear compatible CMOS (LC2MOS) process,which provides low power dissipation yet achieves a highswitching speed and a low on resistance.The on-resistance profile is very flat over the full analog inputrange, ensuring good linearity and low distortion when switchingaudio signals. High switching speed also makes the device suitablefor video signal switching. CMOS construction ensures ultralowpower dissipation, making the device ideally suited for portable,battery-powered instruments.When they are on, each switch conducts equally well in bothdirections and has an input signal range that extends to thepower supplies. In the off condition, signal levels up to thesupplies are blocked. All switches exhibit break-before-makeswitching action for use in multiplexer applications. Low chargeinject is inherent in the design.Product Highlights Extended signal range. The ADG333A is fabricated on an enhanced LC2MOS process, giving an increased signal range which extends to the supply rails. Low power dissipation. Low RON. Single-supply operation. For applications in which the analog signal is unipolar, the ADG333A can be operated from a single rail power supply. The device is fully specified with a single 12 V supply. Applications Audio and video switching Battery-powered systems Test equipment Communication systems
