The MAX4789EUK+ is a high-performance, low-voltage, single-pole/double-throw (SPDT) analog switch from Maxim Integrated, designed to deliver precision and durability for a wide range of applications. Operating from a single +1.8V to +5.5V supply, it's suitable for portable battery-powered devices and other low-voltage systems.

With its ultra-low on-resistance (R_ON) of just 0.5Ω (typical) at +5V, this switch ensures minimal signal distortion and power loss, making it ideal for precision analog signal routing. The R_ON is matched between channels to within 0.05Ω (typical) and is flat (0.2Ω typical) over the specified signal range, providing excellent linearity and low signal attenuation.

The MAX4789EUK+ features a single digital control input to switch the signal path between the normally open (NO) and normally closed (NC) terminals. It also offers high current handling capabilities, with a continuous current of up to 300mA, making it robust for driving heavier loads. Its ESD protection exceeds ±15kV Human Body Model, which ensures that the device is safeguarded against the detrimental effects of electrostatic discharge during handling and operation.

Maxim Integrated has designed the MAX4789EUK+ with a low power consumption in mind, drawing a mere 0.01µA (max) in the off condition, which helps extend battery life in portable applications. Additionally, this analog switch features a fast switching speed of 20ns (max) for turn-on and 15ns (max) for turn-off, allowing for rapid signal switching that is essential in high-speed communication and data acquisition systems.

This versatile switch comes in a compact SOT23-5 package, making it an excellent choice for space-constrained applications. Whether it's for audio and video signal routing, low-voltage data acquisition systems, battery-powered devices, or communication systems, the MAX4789EUK+ from Maxim Integrated is a reliable and efficient solution for your analog switching needs.
