MAX4603EAE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4603EAE+T is a quad single-pole single-throw (SPST) CMOS analog switch featuring two normally open and two normally closed channels. It operates from a single supply of +4.5V to +36V or dual supplies of ±4.5V to ±20V. The device guarantees a maximum on-resistance of 2.5Ω with a match between channels of 0.5Ω max and flatness of 0.5Ω max over the signal range. Rail-to-Rail signal handling is supported, with off-leakage current limited to 2.5nA maximum at +85°C. Turn-on time is typically 160ns and turn-off time is typically 190ns under dual supply conditions.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4603 and other variants in the series?

The MAX4603 features two normally open and two normally closed switches, whereas the MAX4601 has four normally closed switches and the MAX4602 has four normally open switches.

How does the device handle rail-to-rail signals?

Each switch can handle Rail-to-Rail analog signals, allowing the input voltage to swing from the negative supply to the positive supply without clipping.
