The MAX398ESE+ is part of the MAX398 family of multiplexers and demultiplexers. It is a versatile general purpose analog switch that is designed for both digital and analog switching applications. The MAX398ESE+ is an integral part of many analog and digital systems, such as security systems, telecommunication systems and consumer electronics. It is also a popular choice for audio and video applications.

The MAX398ESE+ is a field effect transistor (FET) switch with a high frequency bandwidth of 450 MHz and a bandwidth to capacitance ratio of 15:1. The switch is designed to operate from a single DC voltage supply or dual AC/DC voltage supplies and has a wide operating temperature range from -55 to +125°C. The MAX398ESE+ is extremely low on power consumption, with power consumption of just 4 mA per channel. This makes it an ideal choice for applications where power savings is important.

The MAX398ESE+ offers superior channel-to-channel isolation, with a channel-to-channel crosstalk of -45 dB at 100 MHz. It also features simultaneous analog and digital switching capability and a two-pole single-throw (2PST) configuration. The switch can be connected to any common logic device, such as TTL, CMOS or ECL, and is also RoHS compliant.

The MAX398ESE+ works by using a voltage-controlled voltage source (VCVS) switch, which allows it to change between two voltage signals on opposite sides of the switch. A VCVS switch works by changing the current flow in a circuit by controlling the voltage applied to the gate terminal of the switch. The current flow through the switch is then changed to match the output voltage that is applied to the switch. The two voltage signals can either be digital (on/off) or analog (varying voltage). When an input is applied to the switch, the current flow is then adjusted to match the output voltage.

The MAX398ESE+ also has low on-resistance of typically less than 0.5 ohms and low off-capacitance of typically less than 1 pF, making it ideal for a wide range of applications, including audio/video switching and filtering. The switch is capable of handling up to 40V of peak-to-peak voltage and can work at up to 28V of DC voltage.

The MAX398ESE+ has a wide range of applications, including multiplexing in telecommunication systems, analog signal switching in audio/video systems, digital signal switching in security systems, low-power switching in consumer electronics and much more. Its wide bandwidth and high performance capabilities make it an ideal choice for many applications.

In summary, the MAX398ESE+ is a versatile FET switch that is designed to be used in various multimedia, telecommunication and consumer electronics applications. Its high frequency bandwidth, low power consumption and wide operating temperature range make it an excellent choice for many applications. It is a reliable and cost-effective solution for switching and filtering applications.
