Optimized for ±15-V high-precision low-noise signal switching in data acquisition, T & M, and medical systems, the eight-channel DG508B and dual four-channel DG509B CMOS analog multiplexers provide an extended maximum voltage rating to 44 V, with rail-to-rail analog capability, and can be operated in either a dual- or single-supply configuration. The devices are fabricated on an enhanced SG-II CMOS process with channel off-leakage typically less than 3 pA in a wide analog signal range.
The source-off parasitic capacitance is minimized to 3 pF, and charge injection is less than 2 pC. The devices consume typically 10 μA at 25°C with a guaranteed maximum of 600 μA over temperature. Both are available in 16-pin SOIC and TSSOP packages with an extended temperature range of –40° to 125°C. ($1.15 ea/1,000 — prod qty, July 2009.)
