Siliconix A Member of the TEMIC Group CMOS Analog Switches DG304A/305A/306A/307A Features Benefits Applications @ +15-V Input Range @ Full Rail-to-Rail Analog Signal Range Low Level Switching Circuits @ Fast Switchington: 110 ns @ Low Signal Error Porgrammable Gain Amplifiers @ Low rpgyony: 30 2 @ Wide Dynamic Range Portable and Battery Powered Systems Single Supply Operation @ Low Power Dissipation CMOS Logic Levels Micropower: 30 nW 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. Designed on the Siliconix PLUS-40 CMOS process to achieve low power consumption and excellent on/off switch performance, these switches are ideal for battery powered 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. 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.
