DESCRIPTION
The DG441B, DG442B are monolithic quad analog switches designed to provide high speed, low error switching of analog and audio signals. The DG441B, DG442B are upgrades to the original DG441, DG442.
Combing low on-resistance (45 Ω, typ.) with high speed (tON 120 ns, typ.), the DG441B, DG442B are ideally suited for Data Acquisition, Communication Systems, Automatic Test Equipment, or Medical Instrumentation. Charge injection has been minimized on the drain for use in sample-and-hold circuits.
