The DG407CJ is an integrated circuit that enables switching, multiplexing, or mixing of low or high frequency analog or digital signals with good linearity and low noise. The DG407CJ is designed to improve signal accuracy and performance, while being a cost effective solution for multiple interface applications such as switching, multiplexing, and demultiplexing.

The DG407CJ features two eight-channel analog switch/multiplexer sections with a choice of transistor or JFET switches. The parts can be paralleled or daisy-chained on the same bus, allowing for simple circuit design and reducing welding work. The low on-resistance (100 ohms typical) of the DG407CJ switch transistors provides for low switching power and excellent signal-switching OF performance. The switches have an an attenuation of approximately -50 db and a high frequency response of up to 10 gigahertz (GHz).

In addition to its switching functions, the DG407CJ also contains two high-speed demultiplexers with differential inputs for digital and analog signals. The demultiplexers have a high output frequency response up to 1.2 gigahertz. The output level can be set using an external capacitor and the part features an internal regulator for voltage adjustment.

The DG407CJ also features an integrated low-bandwidth filter which is designed to improve the signal-to-noise ratio of the signal by rejecting unwanted noise. The filter is ideal for applications requiring very low signal leakage.

The DG407CJ is primarily designed and used for a wide range of audio, radio frequency (RF), and other analog and digital applications. With its low signal-to-noise ratio, excellent linearity, and low power consumption, the DG407CJ is ideal for medical, telecommunications, and other high-performance applications where signal accuracy and performance are critical.

Overall, the DG407CJ is an ideal solution for interface applications such as switching, multiplexing, and demultiplexing. With its low on-resistance transistors, high-speed demultiplexers, and integrated low-bandwidth filter, the DG407CJ provides superior signal-switching performance and accuracy, making it the perfect choice for any application requiring high performance and accuracy.
