Working Principle: The MAX4355ECQ+TD is a single-hole connectable, low-voltage analog switch designed to provide superior electrical performance. It is based on a CMOS technology and it directly controls a MOSFET switch. The inner working principle is based on the sensing of electrical signals at the gate and the subsequent controlled switching of the drain-source path between two nodes.The switch is operated by applying a voltage to the gate. The applied voltage must be greater than both the threshold voltage and the voltage at the other drain. When the voltage at the gate exceeds the threshold voltage, the switch turns ON and the N-channel and the P-channel MOSFETs of the MAX4355ECQ+TD work in tandem to switch the drain-source path between two nodes.

Advantages: The MAX4355ECQ+TD provides a wide array of advantages over traditional analog switches. Its low on resistance of 25 ohms reduces the power consumption of the connected device. Its low gate charge of 0.75nC reduces the connected device’s power requirements as well, resulting in increased system efficiencies. Additionally, the MAX4355ECQ+TD has a low 1.3ns propagation delay, providing much faster switching times than those of traditional analog switches. Due to its small size, the MAX4355ECQ+TD can easily be mounted onto a PCB, making it possible to integrate its switching capabilities into small-form-factor designs.

Conclusion: The MAX4355ECQ+TD is a single-hole connectable, low-voltage analog switch designed to provide superior electrical performance across a variety of applications. It is ideal for use in high-speed sensor multiplexing, active filtering, summing, and other general switching applications due to its low on resistance, low gate charge, low power consumption and high resolution. The built-in CMOS technology ensures fast switching times of 1.3ns and a low 1.3ns propagation delay, making it possible to achieve high speed, low power and high resolution in a compact package.
