MAX4533EWP+

The MAX4533EWP+ belongs to a family of analog switches, multiplexers, and demultiplexers, manufactured by Maxim Integrated. It is a low voltage, single-pole/single-throw multiplexer (SPST) with a logic/analog interface. This switch has a guaranteed break-before-make operation and is designed to help reduce power consumption in many applications. This article will provide an overview of the MAX4533EWP+ and explain its application fields and working principle.

The MAX4533EWP+ multiplexer is designed for low voltage, low-noise, high-impedance applications, providing a low ON-resistance of 2Ω, which is 50% lower than other switches from Maxim Integrated. This switch also includes integrated protection diodes, which help protect it from voltage transients and electrostatic discharge. The logic-level control input, CS, is adjustable in order to accommodate both 3.3V and 5V logic levels, making it suitable for many applications. For example, it can be used in mobile phones, medical instruments, aerospace systems, and automotive systems, among others.

Working Principle: The MAX4533EWP+ switch uses a 3-pin architecture. The first pin is called SEL and is the control pin used to select the channel of the multiplexer. Pin 2 is the common pin, and the third pin is the connected output. When no control signal is applied to SEL, the two channels of the multiplexer are both open, thus connecting the two pins. When a control signal is applied to SEL, the switch opens the channel that is not connected to SEL and connects the other pin to the output.

The MAX4533EWP+ also provides protection from overvoltage conditions by shutting off both channels if the on-resistance exceeds its rated value. The switch also features a fast switching performance, with a maximum propagation delay of 10ns, and a low power consumption of 10mW. In addition, the low Ron feedback circuit accurately sets the switching time and reduces power consumption by more than 50%.

Conclusion: The MAX4533EWP+ is a low voltage, single-pole/single-throw multiplexer that is designed to help reduce power consumption in many applications. It features a 3-pin architecture, and a guaranteed break-before-make operation. The logic-level control input, CS, is adjustable in order to accommodate both 3.3V and 5V logic levels, making it suitable for a variety of applications. In addition, the MAX4533EWP+ provides protection from overvoltage conditions and a fast switching performance, making it an excellent choice for portable, low-power applications.
