Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Ensure the component matches the required industrial temperature grade and voltage ratings for your design. Cross-reference the datasheet revision to confirm pinout compatibility and electrical characteristics before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when differential signal routing with low distortion is required. The ADG1209 handles four differential pairs, whereas the ADG1208 handles eight single-ended channels. Consider the 120 Ω on-resistance and 550 MHz bandwidth for high-speed applications. Verify that the 3 V logic interface aligns with your system's control voltage levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG1208/ADG1209 family of low capacitance analog multiplexers. The ADG1209 specifically provides four differential channels controlled by two address bits. It utilizes iCMOS technology to achieve high performance in a compact footprint. The family is designed for applications requiring precise signal switching with minimal glitch energy.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG1208 serves as the single-ended counterpart within the same family. For higher channel counts, consider the ADG1408L. Verify pinout compatibility if substituting with other Analog Devices multiplexers, as package variations exist within the product line.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the ADG1208 and ADG1209?

The ADG1208 switches one of eight single-ended inputs to a common output, while the ADG1209 switches one of four differential input pairs to a common differential output.

How does the EN pin function?

The EN pin is an active-high digital input. When low, all switches are disabled and turned off. When high, the Ax logic inputs determine which channel is active.

What is the typical charge injection value?

The charge injection is typically less than 1 pC over the full signal range, ensuring minimal glitch impulse during switching.
