| DG5043 Vishay Siliconix Monolithic General-Purpose CMOS Analog Switch FEATURES D D D D "15-V Input Range On-Resistance: <50 W Break-Before-Make Switching TTL and CMOS Compatible BENEFITS D D D D Improved Signal Headroom Reduced Switching Errors No Shorting of Inputs Simple Interfacing APPLICATIONS D Audio Switching D Instrumentation D Battery Powered Systems DESCRIPTION The DG5043 solid state analog switch is recommended for general purpose applications in instrumentation, and process control. Built on the Vishay Siliconix PLUS-40 high voltage CMOS process, this device provides ease-of-use and performance advantages to the system designer. Key performance features of the DG5043 are 1-ms switching, low power supply requirements, and break-before-make switching. Each switch conducts equally well in either direction, when on, and blocks up to 30 V peak-to-peak when off. Off leakage current is 1-nA maximum. An epitaxial layer prevents latch up. For new designs, DG403 is recommended.
