MAX4580/MAX4590/MAX4600 dual analog switches feature low on-resistance (1.25Ω max).
The MAX4580, MAX4590 and MAX4600 are dual SPST CMOS analog switches featuring a low on‑resistance of 1.25 Ω max and matched channels (0.25 Ω max). They handle rail‑to‑rail signals, operate from +4.5 V to +36 V single‑supply or ±4.5 V to ±20 V dual‑supply, and provide TTL/CMOS‑compatible logic inputs (0.8 V / 2.4 V thresholds).\n\nThe devices offer low off‑leakage (2.5 nA max at +85 °C), fast switching (typical tON 150 ns, tOFF 200 ns), and robust ESD protection (>2 kV). Package options include 16‑pin SSOP, Wide‑SO, and Plastic DIP, with detailed ordering information and test circuit diagrams included.
