Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel quantity. The BRJ designation indicates the 5-lead SOT-23 package. Confirm RoHS compliance status as manufacturing processes may update lead-free specifications over time. Ensure the source document matches the exact part number to avoid confusion with similar variants like the ADG701L series which have different leakage guarantees.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low power consumption and high speed are critical constraints. The 5-lead SOT-23 package offers a small footprint for space-constrained PCB layouts. Consider the on resistance variation across temperature if precise linearity is required over wide ranges. Verify that the digital control voltage levels match the system's logic family, as the input thresholds vary between 1.8 V and 5.5 V supply rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG701/ADG702 family of low-voltage CMOS switches. It shares functional characteristics with other members of the series but differs in pin count and package configuration. The ADG701 variant provides a single SPST channel, whereas the ADG702 offers dual channels. The BRJ suffix specifically identifies the 5-lead SOT-23 surface-mount option within the broader product portfolio.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG701L series serves as a related alternative with guaranteed leakage specifications. Other general-purpose CMOS switches may offer similar electrical performance but require verification of pin compatibility and package dimensions. Direct pin-for-pin replacements should be evaluated against the absolute maximum ratings and switching speed requirements of the original design.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum analog signal range for the ADG701?

The analog signal range extends from ground (0 V) to the positive supply voltage (VDD), allowing for rail-to-rail operation.

How does the on resistance vary with supply voltage?

The on resistance increases as the supply voltage decreases. At 5 V, it is typically 2 Ω, while at lower voltages such as 1.8 V, it can rise significantly, affecting signal integrity.

Is the ADG701 sensitive to electrostatic discharge?

Yes, the device is ESD sensitive. Although it includes internal protection circuitry, proper handling precautions are recommended to prevent permanent damage or performance degradation.
