NLV14053BDG is a general purpose analog switch in a very small package, which make it suitable to be used in a number of applications. It is a four-mode switching device, which includes analog switch, multiplexer, demultiplexer, and recovery switch. It can be used as an analog switch in a variety of applications, or as a multiplexer or demultiplexer in a system requiring one or more of these functions. The unique features of NLV14053BDG make it ideal for many applications which require a small analog switch.

Application Fields

NLV14053BDG is widely used in various applications, including industrial automation and control systems, data communication systems, audio systems, instrumentation, and other medium to high speed digital systems. In industrial automation and control systems, NLV14053BDG is used as an analog switch for analog signal routing and data switching between two systems. In data communication systems, it is used for switching of data (eg. Ethernet) between two systems. In audio systems, it is used to switch audio signals between two systems. And in instrumentation, it is used for switching of instrumentation signals. In addition to these applications, NLV14053BDG is also used in mobile phone antenna switching, power management, and power amplifier switching.

Working Principles

The NLV14053BDG has a differential analog switch with up to 5 effective analog I/O ports (4 bidirectional and 1 unidirectional) and 1 digital input port. The analog I/O ports, GD and A2/A2+ can be used as either a single analog switch or as multiplexers/demultiplexers, depending on user needs. In single switch operation, the switch can connect one A2/A2+ port to one GD port. In multiplexer/demultiplexer operation, the switch can connect one A2/A2+ port to up to 4 GD ports. There is also a recovery switch which can be used in applications where both a digital and an analog signal are present. The pins of the NLV14053BDG are pulled down to default level when the device is in reset state. When the digital input pin, G1 is high, the NLV14053BDG is enabled and the switches are turned on. The output of the switches is determined by the analog inputs A2/A2+ and GD. Depending on the application, the switches can be used to connect different circuits, or as a multiplexer and/or demultiplexer to switch between different analog signals.

Conclusion

NLV14053BDG is a general purpose analog switch in a small package and can be used for a variety of applications, including industrial automation and control systems, data communication systems, audio systems, and instrumentation. The switch can operate in single switch or multiplexer/demultiplexer mode, and also includes one recovery switch which is used when both a digital and an analog signal are present. NLV14053BDG is ideal for applications which require a small analog switch.
