The DG409CJ+ range of product is a family of monolithic CMOS analog multiplexer ICs (Integrated Circuit) designed for a variety of applications. They are expansively used for analog signal switching, signal multiplexing and demultiplexing applications.

In a nutshell, the device is a type of single-ended reflective analog multiplexer which contains two channels of 4:1 input multiplexer, one 4-bit binary address network, a 4-bit latch and an output buffer with a single output. The DG409CJ+ is capable of switching single-ended analog signals, including offset voltages and currents up to a peak of 5mA.

The component has four inputs and one output. The data sheet of the component indicates all four inputs are equipped with independent signal conditioners providing precise input matching with external reference tests. The component also has an on-chip voltage reference with temperature compensation.

The application field of the DG409CJ+ component varies from signal conditioning for DACs, ADC, Signal Generator, Buffer, DAC Switching and multiplexing, audio and video switching, DC signal switching, level shifting, signal routing and amplifier stages. The component is an ideal device for mixer and monitor applications.

The component is available in SMD (Surface Mount Device) packaged form having standard lead spacing. It can be used for operating environment of commercial as well as industrial applications between -40°C to +85°C.

The component is operated using a single 4-bit binary address. The address input is latched on the falling edge of the address enable (AE) signal. When the address is established, the component is then enabled to reflect the signal that is connected to the selected input. With the help of the FEAT pin, the required reference voltage can be attained to reduce distortion and switch “on” the selected input. The DG409CJ+ is usually operated with a logic power supply voltage in the 0.8V to 5.5V range.

With its easy operation, it is a great and cost-effective solution for analog multiplexer applications. In addition, the component is orthogonal in dimensions measuring 9.75mm x 5.80mm x 1.05mm with maximum height of 1.20mm. The DG409CJ+ component is a reliable device offering excellent RON (On resistance) of 40ohms and high voltage handling capability at 8.0V.
