Description

The ADG1204 is a complementary metal-oxide semiconductor(CMOS) analog multiplexer, comprising four single channelsdesigned on an iCMOS (industrial CMOS) process. iCMOS® is amodular manufacturing process that combines high voltage CMOSand bipolar technologies. It enables the development of a widerange of high performance analog ICs capable of 33 V operationin a footprint that no previous generation of high voltage deviceshas been able to achieve. Unlike analog ICs using conventionalCMOS processes, iCMOS components can tolerate high supplyvoltages while providing increased performance, dramaticallylower power consumption, and reduced package size.The ultralow capacitance and charge injection of this multiplexermakes it an ideal solution for data acquisition and sample-andholdapplications, where low glitch and fast settling are required.Fast switching speed coupled with high signal bandwidth makesthe device suitable for video signal switching. iCMOS constructionensures ultralow power dissipation, making the device ideallysuited for portable and battery-powered instruments.The ADG1204 switches one of four inputs to a common output, D,as determined by the 3-bit binary address lines: A0, A1, and EN.Logic 0 on the EN pin disables the device. Each switch conductsequally well in both directions when on and has an input signalrange that extends to the supplies. In the off condition, signallevels up to the supplies are blocked. All switches exhibit break-before-makeswitching action.Product Highlights 1. 1.5 pF off capacitance (±15 V supply). <1 pC charge injection. 3 V logic-compatible digital inputs: VIH = 2.0 V, VIL = 0.8 V.
