| DG303A_MIL Vishay Siliconix CMOS Analog Switches (Obsolete for non-hermetic. Use DG303B as pin-for-pin replacements.) 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 APPLICATIONS D Full Rail-to-Rail Analog Signal Range D Low Level Switching Circuits D Low Signal Error D Programmable Gain Amplifiers D Low Power Dissipation D Portable and Battery Powered Systems DESCRIPTION The DG303A_MIL is a monolithic CMOS switch in a DPST configuration 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.
