DESCRIPTION
The DG441B/442B are monolithic quad analog switches designed to provide high speed, low error switching of analog and audio signals. The DG441B/442B are upgrades to the original DG441/442.
Combing low on-resistance (45 Ω, typ.) with high speed (tON 120 ns, typ.), the DG441B/442B 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.
