DG407DYZ-T

Analog switches, multiplexers, and demultiplexers are useful components for providing a single input/output for multiple signals. The DG407DYZ-T is one such component, and it is typically used in applications such as multiplexing/demultiplexing analog and digital signals, sample-and-hold circuits, and audio/video systems.

The DG407DYZ-T provides a low on-resistance of 4 Ω, which allows it to switch quickly and efficiently between multiple signals. It also operates on a low supply voltage of 3V, making it suitable for portable and battery-operated devices. The device is designed to reject any common-mode signals that are present in the environment, making it a robust choice for applications in harsh working environments.

The DG407DYZ-T is composed of two electrically isolated analog multiplexers with dual 4-channel inputs and one single output. Each multiplexer is controlled by two independent enable pins, making it possible to switch between four channels. When the enable pin of each multiplexer is high, the output is connected to the selected input channel; when the enable pin is low, the output is disconnected from the input signals.

The DG407DYZ-T operates by sensing the logic level on the enable pins and then switching the corresponding multiplexers to either connect or disconnect the output from the selected input channel. The logic level of the enable pins must be maintained to ensure a correct operation of the device. It is important to note that the DG407DYZ-T is not capable of amplifying the input signals, and thus it is not suitable for applications such as digital-to-analog conversion.

In conclusion, the DG407DYZ-T is a versatile analog switch, multiplexer, and demultiplexer device that is commonly employed in cases where a single input/output is required for multiple signals. Its low on-resistinace, low supply voltage, and common-mode rejection capabilities make it a robust solution for applications in harsh environments. However, the device has limited functionality and is not suitable for applications that require signal amplification.
