| DG304A/305A/306A/307A Vishay Siliconix CMOS Analog Switches FEATURES D D D D D D "15-V Input Range Fast Switching--tON: 110 ns Low rDS(on): 30 W Single Supply Operation CMOS Logic Levels Micropower: 30 nW BENEFITS D D D D Full Rail-to-Rail Analog Signal Range Low Signal Error Wide Dynamic Range Low Power Dissipation APPLICATIONS D Low Level Switching Circuits D Programmable Gain Amplifiers D Portable and Battery Powered Systems DESCRIPTION The DG304A through DG307A series of monolithic CMOS switches were designed for applications in communications, instrumentation and process control. This series is well suited for applications requiring fast switching and nearly flat on-resistance over the entire analog range. applications, without sacrificing switching speed. Break-before-make switching action is guaranteed, and an epitaxial layer prevents latchup. Single supply operation (for positive switch voltages) is allowed by connecting the V- rail to 0 V. Designed on the Vishay Siliconix PLUS-40 CMOS process to achieve low power consumption and excellent on/off switch performance, these switches are ideal for battery powered Each switch conducts equally well in both directions when on, and blocks up to the supply voltage when off. These switches are CMOS input compatible.
