The DG405CY is an IC (integrated circuit) component that is widely used in electronic systems for signal switching and routing applications. It belongs to the family of analog multiplexers and demultiplexers, and offers several key features that make it popular among engineers and designers. Here is an overview of the DG405CY and its key features:
1. Functionality: The DG405CY is a quad, single-pole, double-throw (SPDT) analog switch. Each of the four switches in the IC can independently connect one of the two input signals to the common output terminal. This functionality allows for the routing or switching of analog signals from various sources to a desired destination.
2. Voltage range: The component operates over a wide voltage range, typically from ±5V to ±22V. This characteristic enables compatibility with a broad range of power supplies commonly used in electronic systems.
3. Low ON resistance: The DG405CY has a very low ON resistance, measuring typically around 80 ohms. This low resistance ensures minimal signal loss during the signal routing process, resulting in accurate and undistorted transmission.
4. High off-isolation: The IC provides excellent off-isolation performance, typically around -80dB at 1MHz. This high off-isolation characteristic ensures that the undesired signals from the non-selected inputs are attenuated effectively, reducing any cross-talk or interference between signal paths
