The MAX4603EAE+ is a monolithic CMOS analog switch and multiplexer with five integrated switches and an ultra-low power consumption. It is part of the MAX family of CMOS analog switches and multiplexers, designed to provide high performance and low power consumption while maintaining optimum pulse-width distortion and low leakage current.

As an analog switch, the MAX4603EAE+ can accept input signals ranging from 0V to 5V, or 0V to 6V. It is capable of switching signals with a maximum switching frequency of 100kHz. The switch also has a low side-injection current (20mA max), and is capable of contant current operation when driving capacitive loads up to 8 uF. It is available in 6-pin SOT-23 and SC-70 packages.

The MAX4603EAE+ is also a multiplexer, and provides 8 data channels to select from. It has two enable pins, one for output and another for addressing. It can be used to switch between up to 8 analog signals or multiplex 8 digital signals. The MAX4603EAE+ also provides differential input and output paths, allowing for improved noise immunity.

The device operates with a minimum analog voltage range of -0.3V to +5.5V, and can be powered with a single +3V to +18V supply, making it ideal for a wide range of applications. It is suitable for use in medical, retail, industrial and automotive electronics.

The MAX4603EAE+ has a floating channel structure that enables it to be used in both single-ended and differential modes. It utilizes CMOS technology to provide both a low off-state resistance and high on-state conductance. Additionally, the MAX4603EAE+ has low crosstalk between channels, allowing for improved signal integrity in multiplexed applications.

The working principle of the MAX4603EAE+ is based on two complementary NMOS transistors. The two transistors are arranged in an open-drain configuration, with one transistor conducting when the other is turned off. By applying appropriate signals to the control inputs, the transistors are either on or off, allowing current to flow through the switch. This switching action is performed with low resistance and minimal leakage current, providing reliable and efficient operation.

The MAX4603EAE+ is a highly versatile analog switch and multiplexer designed for use in a variety of applications. Its combination of low power consumption, low resistance, and high on-state conductance make it suitable for use in various control, switching, and mixing circuits. Additionally, its differential input and output paths allow for improved noise immunity, making it ideal for use in rapid switching and high-speed sampling systems.
