This document introduces the MAX4604/MAX4605/MAX4606 switch.
The MAX4604, MAX4605 and MAX4606 are quad analog switches featuring a maximum on‑resistance of 5 Ω and matched channel resistance within 0.5 Ω. Each switch handles rail‑to‑rail analog signals and offers off‑leakage currents as low as 2.5 nA at +85 °C, making them suitable for low‑distortion applications and as replacements for mechanical relays.
These devices operate from a single supply of +4.5 V to +36 V or from dual supplies of ±4.5 V to ±20 V, with TTL/CMOS‑compatible control inputs (logic low 0.8 V, logic high 2.4 V). The data sheet includes absolute maximum ratings, electrical characteristics, dynamic switching parameters, and application notes such as over‑voltage protection and layout considerations.
