The MAX4661/MAX4662/MAX4663 are quad analog switches with low on-resistance and flat switching characteristics. They are suitable for low-distortion applications and can replace mechanical relays. These switches have lower power requirements, use less board space, and are more reliable than mechanical relays.
The MAX4661, MAX4662, and MAX4663 are quad analog switches featuring low on‑resistance (2.5 Ω max) and low off‑leakage (5 nA max at 85 °C). They support rail‑to‑rail signal handling and operate from a single +4.5 V to +36 V supply or dual ±4.5 V to ±20 V supplies, with TTL/CMOS‑compatible control inputs.
The datasheet provides absolute maximum ratings, detailed electrical characteristics, switching timing, pin‑out diagrams, ordering information, and package details for SSOP, SO, and DIP formats. It also includes application notes such as reed‑relay replacement and over‑voltage protection recommendations.
