The MAX4704 is a low-voltage, 4-channel analog multiplexer that operates from a single +1.8V to +5.5V supply. The device features break-before-make switching action with a tON = 60ns and tOFF = 20ns at +3V. When powered from a +2.7V supply, the device has a 60Ω (max) on-resistance (RON), with 3Ω (max) RON matching and 5Ω max RON flatness. The digital logic inputs are 1.8V-logic compatible from a +2.7V to +3.3V supply. The MAX4704 is available in both a space-saving 12-pin QFN (3mm x 3mm) package and a 10-pin µMAX package. The device can be used in a variety of applications, including MP3 players, battery-operated equipment, relay replacement, audio and video signal routing, low-voltage data-acquisition systems, communications circuits, PCMCIA cards, cellular phones, and modems.
The MAX4704 analog multiplexer operates from a single +1.8 V to +5.5 V supply and offers break‑before‑make switching with a 60 ns turn‑on and 20 ns turn‑off time. It features a guaranteed on‑resistance of up to 60 Ω at a +2.7 V supply, with channel matching of 3 Ω and flatness of 5 Ω.
Available in a 12‑pin QFN (3 mm × 3 mm) and a 10‑pin µMAX package, the device supports rail‑to‑rail signal handling, low leakage (100 pA), high off‑isolation (‑85 dB at 1 MHz), and a bandwidth greater than 200 MHz, making it suitable for MP3 players, battery‑operated equipment, audio/video routing, and low‑voltage data‑acquisition systems.
