Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix corresponds to the specific package variant required, as the ADG701L family includes MSOP, SOT-23-6, and SOT-23-5 options. Confirm RoHS compliance status via the manufacturer's documentation, as indicated by the 'Z' suffix in related part numbers. Ensure the selected component matches the industrial temperature range specifications for your operational environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single-pole single-throw configuration is needed with minimal on-resistance variation. The 5-lead SOT-23 package offers a compact footprint for space-constrained designs. Consider the 200 MHz bandwidth for high-frequency signal paths and the low supply current for energy-sensitive projects. Verify that the digital control inputs are compatible with the system logic levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG701L/ADG702L series of CMOS low-voltage switches. It shares architectural similarities with other members of the family but differs in channel count and package type. The ADG701L specifically provides a single switch, whereas the ADG702L offers dual channels. The BRJZ suffix indicates the 5-lead SOT-23 package option within this product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements must match the single SPST configuration and 5-lead SOT-23 package. Components like the ADG701BRTZ offer similar electrical characteristics but utilize a 6-lead SOT-23 package, requiring PCB layout adjustments. Ensure any substitute maintains the 1.8 V to 5.5 V supply range and comparable on-resistance specifications.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the supply voltage affect the on-resistance?

The on-resistance varies with the supply voltage; for example, at 1.8 V operation, the typical on-resistance increases to approximately 40 Ω compared to 2 Ω at higher voltages.

What is the off-isolation performance at high frequencies?

Off-isolation remains better than −75 dB up to roughly 1 MHz and stays above −55 dB up to 10 MHz, degrading as frequency increases due to parasitic capacitance.

Is the device suitable for rail-to-rail signal handling?

Yes, the ADG701L supports rail-to-rail operation, allowing the analog signal range to extend from 0 V to VDD without significant distortion.
