| DG300A/301A/302A/303A Vishay Siliconix CMOS Analog Switches FEATURES D D D D D D Analog Signal Range: "15 V Fast Switching--tON: 150 ns Low On-Resistance--rDS(on): 30 W Single Supply Operation Latch-up Proof CMOS Compatible BENEFITS D Full Rail-to-Rail Analog Signal Range D Low Signal Error D Low Power Dissipation APPLICATIONS D Low Level Switching Circuits D Programmable Gain Amplifiers D Portable and Battery Powered Systems DESCRIPTION The DG300A-DG303A family of monolithic CMOS switches feature three switch configuration options (SPST, SPDT, and DPST) for precision applications in communications, instrumentation and process control, where low leakage switching combined with low power consumption are required. In the on condition the switches conduct equally well in both directions (with no offset voltage) and minimize error conditions with their low on-resistance. Designed on the Vishay Siliconix PLUS-40 CMOS process, these switches are latch-up proof, and are designed to block up to 30 V peak-to-peak when off. An epitaxial layer prevents latchup. Featuring low power consumption (3.5 mW typ) these switches are ideal for battery powered applications, without sacrificing switching speed. Designed for break-before-make switching action, these devices are CMOS and quasi TTL compatible. Single supply operation is allowed by connecting the V- rail to 0 V.

This facilitates their use in applications where only one supply is available. The trade-offs of using single supplies are: 1) Increased rDS(on); 2) slower switching speed. The analog voltage should not go above or below the supply voltages which in single operation are V+ and 0 V.
