Analog switches, multiplexers, and demultiplexers are common integrated circuits used in different kinds of electrical engineering applications. The SJM181BXA is one such integrated circuit that provides impressive features and capabilities for applications such as ADCs and DACs. This article will discuss the application field and workings of the SJM181BXA.

Overview of the SJM181BXA

The SJM181BXA is an integrated circuit made by Shanghai Shijin Instrument Company. It is an analog switch IC that functions as both a multiplexer and demultiplexer. The SJM181BXA has a total of 40 pins, including one input pin and four output pins. It operates at a 5V supply voltage, and consumes up to 10 mA of current in order to function.

In terms of its features, the SJM181BXA has two sets of control pins: two pins for the multiplexer and two pins for the demultiplexer. It also has an enable pin (EN) which turns the device on and off, and a latch pin (LS) which can be used to store data. Moreover, the SJM181BXA offers robust performance in terms of its logic levels and output waveforms. This makes it suitable for a wide range of applications.

Application Field of the SJM181BXA

The application field of the SJM181BXA is wide, ranging from audio/video applications to automotive and industrial applications. In audio/video applications, this integrated circuit can be used as an analog switch for controlling the flow of audio or video signals. It is also suitable for use in ADCs and DACs, as it can multiplex and demultiplex signals according to user-specified settings used in these devices.

In automotive and industrial applications, the SJM181BXA can be used to control the signal flow through different circuits and devices. Additionally, it can be used as a signal multiplexing/demultiplexing IC for controlling signal relay and signal conversion in these applications. Furthermore, the SJM181BXA can be used for controlling switch states, as it has an enable pin and a latch pin that can be used to select and store different settings.

Working Principle of the SJM181BXA

The working principle of the SJM181BXA can be broken down into three main steps: (1) multiplexing, (2) demultiplexing, and (3) switching. When multiplexing is enabled, the SJM181BXA uses the two control pins to select which of its four output pins will receive the input signal. As for the switching function, the SJM181BXA can be enabled or disabled using its enable pin, and its latch pin can be used to store settings for controlling whether the switching is on or off.

When the demultiplexing feature is enabled, the two control pins are used to select which of the four output pins will receive the input signal. The SJM181BXA also uses its enable pin to control whether the demultiplexing operation will take place or not. Lastly, the SJM181BXA can also be used for controlling the switching states using its latch pin. When the latch pin is enabled, the settings stored in the latch can be used to control whether the switching will take place or not.

Conclusion

The SJM181BXA is an integrated circuit that provides impressive features and capabilities for applications such as ADCs and DACs. It can be used as an analog switch to control the flow of audio or video signals in audio/video applications. It is also suitable for automotive and industrial applications, as it can be used to control signal switching and signal conversion. The working principle of the SJM181BXA involves multiplexing, demultiplexing, and switching. It also has an enable pin and a latch pin for controlling the device\'s settings. All in all, the SJM181BXA is an integrated circuit that offers impressive features and capabilities for a wide range of applications.
