The DG408LDY is a monolithic CMOS analog switch designed for use in low voltage signal applications, primarily in cellular phones and portable electronic devices. It consists of four switches, each with an independent select signal, that can be configured as a single 4:1 multiplexer, dual 2:1 multiplexers, or individual switches. This device is very power efficient, requiring only microamperes of operating current.

The DG408LDY is a high-performance, low-voltage, low-power integrated analog switch for portable applications where fast switching is needed. It features tiny low-voltage power supplies, low power dissipation, and fast switching speeds of up to 200 ns. Additionally, the device offers both current and voltage levels with low on-resistance and low RON-ON capacitance.

The DG408LDY is a multipurpose device that is applicable in many applications, including low power audio, video and data switching, pulse width modulation, sample and hold circuits, and various logic circuits. The device has four independent operation channels, each with its own select signal. It also allows multiplexing of either digital or analog signals.

The DG408LDY is designed to operate in both single-ended and differential signaling modes. The differential mode allows the device to be used as a differential amplifier. Its LP3 power-saving feature reduces its operating current from 1.8mA to only 80uA when it is not switching. This feature also reduces the DC power consumption when compared to the traditional CMOS switch.

The DG408LDY works in a variety of applications, including low power audio and video switching, logic circuits, multiplexing and demultiplexing, pulse width modulation, and sample and hold circuits. To use the device in these applications, it requires a negative voltage rail of -1.5V, a positive voltage rail of +3.6V, and a total supply current of only 4.0mA. It also features a wide frequency response range of DC to 100 MHz.

The DG408LDY is able to switch both unidirectional and bidirectional signals. Its four independent logic input signals enable the device to operate as either a single 4:1 multiplexer, dual 2:1 multiplexers, or four individual switches. The logic inputs are enabled with an input voltage of 0-3.6V. When no input is applied, the switching path is off and the device won’t transfer any data.

When the DG408LDY is used as a multiplexer, it can be connected to two differential inputs and two select signals. Depending on the state of the two select signals (low or high), one different input can be selected. All four of the DG408LDY’s channels can be connected together too, allowing it to be used as a single 4:1 multiplexer.

In conclusion, the DG408LDY is a versatile analog switch designed for use in portables and cell phones. This multipurpose device offers a wide frequency response and low power dissipation, as well as several multiplexer options. Although it is primarily used for signal switching, it can also be used for logic circuits, multiplexing and demultiplexing, sample and hold circuits, and pulse width modulation.
