Each switch connects a common I/O pin to one of four channels, with the two sections operating in parallel or independently depending on the enable logic. The -92 dB crosstalk at 100 kHz keeps channel bleed low enough for 16-bit data acquisition and audio-band multiplexing. On-resistance maxes out at 100 ohm, with channel-to-channel matching held to 1.5 ohm — that matching matters when you're switching gain-setting resistors or scaling divider networks where the absolute R_on matters less than the ratio between paths. Switching time is 150 ns for both turn-on and turn-off, fast enough to scan eight channels at several hundred kilohertz without dead-time gaps. Single-supply range is 5 V to 30 V; dual-supply range is ±5 V to ±20 V. The -40 to 85 °C operating range suits factory-floor PLC analog input modules, data loggers, and outdoor telecom line cards. Charge injection is a moderate 2 pC — acceptable for sampled-data systems with a settling-time budget, not for sub-pC precision metrology. ## Lifecycle and sourcing — active, no redesign pressure DG409DY+ has an Active lifecycle status and is ROHS3 Compliant. For a BOM line that needs a dual SP4T mux in 16-SOIC with wide supply range, this is a straightforward procurement — no surplus-broker chasing required. ## Package and handling — 16-SOIC in Tube The part ships in the 16-lead SOIC body (0.154\" wide, 3.90 mm body width) — a common footprint shared by many analog muxes and op-amps. The supplier device package is 16-SOIC, and the listed shipping form is Tube. For high-volume assembly, verify that your pick-and-place feeder accepts Tube input or request Tape & Reel from the distributor at quote time.","metaTitle":"Maxim DG409DY+ Dual SP4T Analog Switch, -92 dB Crosstalk","metaDescription":"DG409DY+ dual SP4T analog multiplexer from Maxim. -92 dB crosstalk at 100 kHz, 100 ohm on-resistance, 150 ns switching.

A through-hole sibling, DG409DJ, exists for prototype boards or legacy sockets — the electrical specs (dual SP4T, 100 ohm R_on, -92 dB crosstalk) are identical; the difference is the 16-pin DIP package versus the 16-SOIC. For a pin-compatible SMT alternative within the same family, the DG409DY+ is the current-production choice."},{"question":"What is the crosstalk rating of DG409DY+?","answer":"Crosstalk is -92 dB at 100 kHz between channels. That figure tells you how much of a signal on one channel bleeds into the other channels — at -92 dB it is low enough for 16-bit audio and precision analog multiplexing below 1 MHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DG409DY","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DG409DY when reusing this data.
