The MAX4599 is a single-channel low-voltage switch produced by Maxim. It operates at a supply voltage of +2.0V to +5.5V, has a switch resistance of 60 ohms, and a switching time of 30ns. It comes in SC70, µDFN, and SOT23 packages.
The MAX4599 is a low‑voltage, single‑supply SPDT analog switch that operates from +2.0 V to +5.5 V. It is offered in 6‑pin SC70, UDFN, and SOT23 packages and is suitable for battery‑operated equipment, audio/video routing, cellular phones, data‑acquisition systems, and other low‑voltage applications.
Key features include 60 mΩ typical on‑resistance at +5 V, fast switching (ton = 30 ns, toff = 25 ns), 5 pC maximum charge injection, 200 MHz -3 dB bandwidth, and low leakage current (0.5 nA at +25 °C). The device provides break‑before‑make operation and TTL/CMOS‑compatible logic levels.
