DG444, DG445 Vishay Siliconix Quad SPST CMOS Analog Switches * Audio switching FEATURES * Low on-resistance: 50 * Battery powered systems * Low leakage: 80 pA * Data acquisition * Low power consumption: 22 nW * Sample-and-hold circuits * Fast switching action - tON: 120 ns * Telecommunication systems * Low charge injection * Automatic test equipment * DG211, DG212 upgrades * Single supply circuits * TTL/CMOS logic compatible APPLICATIONS * Hard disk drives BENEFITS * Low signal errors and distortion DESCRIPTION * Reduced power supply requirements 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. * Faster throughput * Improved reliability * Reduced pedestal errors * Simple interfacing 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 blocks input voltages to the supply levels when off.
