The ADG1408/ADG1409 are monolithic iCMOS analog multiplexers comprising eight single channels and four differential channels. They have features such as 4.7Ω maximum on resistance, 0.5Ω on resistance flatness, high current, and 3V logic-compatible inputs.
The ADG1408 and ADG1409 are monolithic iCMOS analog multiplexers offering 4‑/8‑channel configurations with low on‑resistance and rail‑to‑rail operation. They support ±15 V, ±12 V and ±5 V supplies and are 3 V logic‑compatible, making them suitable for relay replacement, data acquisition, and battery‑powered instruments.
The document includes detailed specifications such as on‑resistance, leakage currents, dynamic characteristics, and continuous current per channel, as well as functional block diagrams, package dimensions, and an ordering guide for various package options.
