www.vishay.com DG444, DG445 Vishay Siliconix Quad SPST CMOS Analog Switches APPLICATIONS Audio switching Battery powered systems Data acquisition Sample-and-hold circuits Telecommunication systems Automatic test equipment Single supply circuits Hard disk drives DESCRIPTION The DG444, DG445 monolithic quad analog switches are designed to provide high speed, low error switching of analog signals. The DG444 has a normally closed function. The DG445 has a normally open function. Combining low power (22 nW, typ.) with high speed (tON: 120 ns, typ.), the DG444, DG445 are ideally suited for upgrading DG211, DG212 sockets. Charge injection has been minimized on the drain for use in sample-and-hold circuits. To achieve high-voltage ratings and superior switching performance, the DG444, DG445 are built on Vishay Siliconix’s high-voltage silicon-gate process. An epitaxial layer prevents latchup. Each switch conducts equally well in both directions when on, and...
