Maxim Integrated's MAX4634ETB+T Low-Voltage, Single-Supply SPDT Analog Switch

The MAX4634ETB+T 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 component is designed for precision analog signal switching applications, delivering low on-resistance and low cross-talk, making it an ideal choice for a wide range of applications including audio signal routing, data acquisition systems, and communication devices.

Encased in a compact, 10-pin TDFN package, the MAX4634ETB+T is optimized for space-constrained designs. The switch offers fast switching speeds with a transition time of less than 250ns, ensuring minimal signal delay in critical applications. The low on-resistance of less than 0.5Ω is matched between channels to within 0.05Ω and remains flat over the specified signal range, providing excellent linearity and low distortion.

This analog switch also features a break-before-make switching action, which prevents signal disruption by ensuring that one switch is fully off before the other turns on. Additionally, the MAX4634ETB+T is characterized for operation over the extended -40°C to +85°C temperature range, making it suitable for industrial environments where temperature extremes are common.

Another key advantage of the MAX4634ETB+T is its low power consumption. With a quiescent current of less than 1µA, it is an energy-efficient solution for battery-powered devices. The device also includes an active-low enable input that allows the switch to be put into a high-impedance state, further reducing power consumption when the switch is not in active use.

Maxim Integrated's commitment to quality and reliability is evident in the MAX4634ETB+T, which includes electrostatic discharge (ESD) protection exceeding 2000V Human Body Model, ensuring robust performance in the face of electrical transients. Whether it's for audio equipment, data acquisition, or other sensitive analog applications, the MAX4634ETB+T offers designers a reliable and efficient switching solution.

To accommodate various design requirements, the MAX4634ETB+T is fully specified for both single +5V and +3.3V operation, providing flexibility in system design. Its simple logic interface makes it easy to control, and it is suitable for use in both analog and digital applications.
