Each of the two independent switch circuits selects one of four inputs to a common output, giving an 8:2 or 4:2 routing capability depending on wiring. The 450 ohm max on-resistance is the key parametric — it sets the voltage drop across the switch for a given signal current and defines the RC time constant with the load capacitance. For precision analog signals, the 27 ohm channel-to-channel matching keeps gain errors consistent across paths. ## Dual supply range and signal swing Rated for dual supplies from ±4.5 V to ±18 V, the DG509ACWE+ can handle bipolar analog signals up to the supply rails minus the on-resistance drop. This makes it a natural fit for ±5 V, ±12 V, or ±15 V analog backplanes common in test equipment, data acquisition, and audio routing. The 1.5 µs turn-on and 1 µs turn-off times are adequate for low-speed scanning and relay-replacement applications where microsecond-level settling is acceptable. ## Commercial temperature grade — indoor use only The 0°C to 70°C operating range limits this part to commercial environments — office equipment, benchtop instruments, lab gear, and consumer audio. Not rated for industrial or automotive temperature extremes. If the BOM calls for a wider temperature range, look at the industrial-grade variants in the same family (DG509BDJ or similar) that extend to -40°C to +85°C. ## Active lifecycle — no LTB pressure Listed as Active with ROHS3 compliance. For a BOM line that needs a dual 4:1 mux in SOIC-16, this is a low-risk, no-surprise selection.","metaTitle":"Maxim DG509ACWE+ SP4T Analog Multiplexer, 450 Ohm, 16-SOIC","metaDescription":"Maxim DG509ACWE+ dual 4:1 analog multiplexer, 450 ohm max on-resistance, ±4.5V to ±18V dual supply, 0°C to 70°C, 16-SOIC.
