The DG381ACWE+ is a versatile device which can be used in a variety of applications, particularly those that involve analog switches, multiplexers, demultiplexers, and other types of interface-level signal switching and/or conditioning, depending on the model’s configuration and features. In this article, we’ll discuss the different use cases and general working principles of the DG381ACWE+.

General Description

The DG381ACWE+ is a CMOS, monolithic integrated circuit designed for analog signal switching and/or conditioning. The device comes in multiple packages, including 8, 14, 20, and 28 pin dual-in-line packages, which allow for various configurations for signal switching, multiplexing/demultiplexing, differential signal conditioning, and any other applications requiring analog signal switching. The device is CMOS, with static- and dynamic-switch capable styles.

Analog Switching Applications

The DG381ACWE+ can be used in many analog signal switching applications, including the switching in and out of various power supplies and signal paths, providing signal mixing and/or attenuation, and conditioning signal paths for density matching and signal clarity. Two of the more popular configurable features of the DG381ACWE+ include the active clamping feature, which allows the user to reduce crosstalk on high-shape power signals; and the dual-diode emitter follower option, which reduces the VCO and spurious signals when used with precision signal measuring instruments.

Multiplexer/Demultiplexer Workings

The DG381ACWE+ can be used for multiplexing/demultiplexing of on-off signals from various digital sources. It contains two 8-channel multiplexers and two 16-channel demultiplexers which can be configured to accept or reject on-off signals from multiple digital sources. This is done by simply pulling the appropriate signals to ground, thus enabling/disabling them when required.

The multiplexer/demultiplexer circuitry in the DG381ACWE+ is especially helpful when signals are to be routed between multiple digital systems, since it allows the user to isolate and switch between the different signal paths quickly and easily. Additionally, the device features adjustable switching speeds, channel states, and channel stay modes, which can be configured depending on the specific application.

Differential Signal Conditioning

The DG381ACWE+ can also be used for differential signal conditioning. By using the device’s programmable gain and offset circuitry, the user can precisely adjust the timing of the signals being switched, and thereby condition them to spec. The device also incorporates over-temperature protection, which ensures that the signal voltage levels remain consistent and accurate throughout the entire process.

Conclusion

The DG381ACWE+ is a versatile device which provides features and functionality which make it well-suited for a wide range of applications, including analog signal switching and conditioning, multiplexing/demultiplexing, and differential signal conditioning. With its wide range of package sizes and configurable features, the device is the perfect choice for designers looking for a reliable, low-cost solution for their interface-level switch and conditioning needs.
