MAX4601CWE+ [Analog Devices]

The MAX4601/MAX4602/MAX4603 are quad analog switches with low on-resistance (2.5Ω max), matched between channels (0.5Ω max), and flat over the specified signal range. They handle Rail-to-Rail analog signals, have low off-leakage current (2.5nA max at +85°C), and are ideal for low-distortion applications. They operate from a single supply of +4.5V to +36V or dual supplies of ±4.5V to ±20V, with TTL/CMOS-compatible control inputs. These switches are preferred over mechanical relays in automatic test equipment and other applications requiring current switching, offering low power requirements, less board space, and higher reliability.
