MAX4662CAE+ [Analog Devices]

The MAX4661/MAX4662/MAX4663 are quad analog switches with low on-resistance (2.5Ω max), matched between channels (0.5Ω max), and flat over the signal range. They handle Rail-to-Rail analog signals with low off-leakage current (5nA max at +85°C). The MAX4661 has four normally closed switches, MAX4662 has four normally open, and MAX4663 has two NC and two NO with break-before-make switching. They operate from single +4.5V to +36V or dual ±4.5V to ±20V supplies, with TTL/CMOS-compatible logic inputs. Ideal for low-distortion applications, replacing mechanical relays in test equipment and current switching scenarios.
