The ADG1204 is a low capacitance, low charge injection, ±15 V/+12 V 4:1 iCMOS™ Multiplexer, featuring 1.5 pF off source capacitance and <1 pC charge injection, and is suitable for use in automatic test equipment, data acquisition systems, battery-powered systems, sample-and-hold systems, audio signal routing, video signal routing and communication systems.
The ADG1204 is a CMOS analog multiplexer offering four single channels with ultra‑low off‑capacitance (1.5 pF) and charge injection (<1 pC). It operates with either dual supplies (+15 V/–15 V) or a single 12 V supply, providing on‑resistance of 120 Ω (dual) or 300 Ω (single) and typical power consumption below 0.03 µW.
Designed for automatic test equipment, data acquisition, battery‑powered instruments, sample‑and‑hold, audio, video and communication systems, the device features 3‑V logic‑compatible inputs, break‑before‑make switching, and high bandwidth up to 800 MHz (dual) or 550 MHz (single). Pin configurations for TSSOP and LFCSP packages are detailed, along with terminology and absolute maximum ratings.

The on‑resistance is 120 Ω for the dual‑supply version and 300 Ω for the single‑supply version.
The dual‑supply version uses +15 V and –15 V (33 V range), while the single‑supply version operates from 12 V.
Typical power consumption is less than 0.03 µW.
Logic‑compatible inputs require a high voltage of at least 2.0 V and a low voltage no greater than 0.8 V.
