ADG408/ADG409 are 8-channel and 4-channel single-ended/differential high performance analog switches, with a maximum supply voltage range of 44 V, VSS to VDD analog signal range, low on resistance (maximum 100 Ω), low power (ISUPPLY < 75 μA), fast switching, break-before-make switching action, and can replace DG408/DG409
The ADG408 (4‑channel) and ADG409 (8‑channel) are monolithic CMOS analog multiplexers designed on an enhanced LC‑MOS process. They feature a 44 V maximum supply rating, low on‑resistance (100 Ω max), low power consumption, break‑before‑make switching, and extended signal range that reaches the supply rails. Both devices support dual‑supply (±15 V) and single‑supply (5‑12 V) operation.
Typical applications include audio/video routing, automatic test equipment, data acquisition, battery‑powered systems, sample‑and‑hold circuits, and communication systems. The document provides detailed specifications, pin configurations, typical performance curves, and an ordering guide for multiple package options such as PDIP, SOIC‑N, TSSOP, and CERDIP.
