Maxim Integrated MAX4544EUA+ Low-Voltage, Single-Supply SPDT/DPDT Analog Switches

The MAX4544EUA+ from Maxim Integrated is a high-performance, single-pole/double-throw (SPDT) analog switch that operates from a single +1.8V to +5.5V supply. This versatile switch is designed for precision analog signal switching and is ideal for portable and battery-powered applications due to its low power consumption and compact µMAX package.

Featuring low on-resistance (R_ON) of just 0.35Ω (typical) that is matched between channels to 0.03Ω (typical) and is flat (0.03Ω typical) over the specified signal range, the MAX4544EUA+ ensures excellent linearity and low signal distortion. This makes it a suitable choice for a variety of applications, including audio signal routing, battery-powered systems, sample-and-hold circuits, and more.

With its single-supply operation, the MAX4544EUA+ simplifies power supply design and provides for efficient operation. The device also features fast switching speeds (t_ON = 175ns and t_OFF = 145ns typical), which is beneficial for applications requiring quick signal routing changes. Additionally, the switch has a low power consumption with a supply current of only 1µA (max), which contributes to the extended battery life of portable devices.

For design flexibility, the MAX4544EUA+ offers a digital logic input that is TTL and CMOS compatible, allowing for easy interface with a wide range of control logic. Furthermore, the device has an ESD protection of ±2000V, which enhances its reliability and robustness in harsh environments.

The MAX4544EUA+ is available in a space-saving 8-pin µMAX package, which is highly beneficial for applications where board space is at a premium. Its extended temperature range of -40°C to +85°C makes it suitable for industrial applications as well.

In summary, the MAX4544EUA+ from Maxim Integrated is a reliable and efficient solution for designers looking to incorporate a high-quality analog switch in their systems, providing excellent performance in a small footprint.
