Maxim Integrated MAX4521ESE+ Analog Switch

The MAX4521ESE+ is a high-performance, precision analog switch from Maxim Integrated designed to offer superior switching characteristics for a wide range of applications. This component operates with single +5V to +30V or dual ±4.5V to ±20V supply voltages, providing design flexibility and compatibility with various system architectures.

Featuring low on-resistance (R_ON) of just 100Ω (max) and an R_ON matching between channels of 5Ω (max), this analog switch ensures minimal signal distortion and excellent channel-to-channel uniformity. Its R_ON flatness of 6Ω (max) across the specified signal range further guarantees consistent performance regardless of the applied signal voltage, making it ideal for precise analog signal routing.

The MAX4521ESE+ comes in a compact 16-pin narrow SO package, optimizing board space without compromising on functionality. Its low charge injection of 10pC (max) and low power consumption make it an energy-efficient solution for battery-powered devices. Additionally, with an ESD protection rating of ±2000V per Method 3015.7, this analog switch provides robustness against electrostatic discharges, enhancing its reliability in sensitive applications.

With fast switching times (t_ON = 175ns max, t_OFF = 145ns max), the MAX4521ESE+ is suitable for high-speed applications where timing is critical. Its break-before-make switching action prevents signal overlap during channel transitions, ensuring clean, glitch-free signal routing.

Applications for the MAX4521ESE+ are diverse and include use in sample-and-hold circuits, communication systems, audio signal routing, data acquisition systems, and other analog signal multiplexing/demultiplexing scenarios. Its high-level integration and performance characteristics make it a preferred choice for designers looking to optimize their system's signal integrity and operational efficiency.

In summary, Maxim Integrated's MAX4521ESE+ analog switch offers a combination of low on-resistance, fast switching, and high ESD protection, making it a versatile and reliable component for a multitude of analog switching applications.
