ADG708CRU

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG708CRU is an 8-channel analog multiplexer in a 16-lead TSSOP package. It operates on a single supply from 1.8 V to 5.5 V or dual supplies of ±2.5 V. Key electrical parameters include a typical on resistance of 3 Ω, maximum switching time of 14 ns, and leakage currents of 100 pA. The device features TTL- and CMOS-compatible inputs, guaranteed break-before-make switching, and an operating temperature range of -40°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Supports single-supply operation from 1.8 V to 5.5 V and dual-supply configurations up to ±2.5 V.
• Features low on resistance with high flatness for minimal signal distortion across the full voltage range.
• Includes an enable input to disable all channels simultaneously, reducing power consumption.
• Guaranteed break-before-make switching action prevents momentary shorting during channel transitions.

• Battery-powered portable instruments

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against the manufacturer's ordering guide to confirm package type and compliance status. The 'RU' designation indicates a 16-lead Thin Shrink Small Outline Package. Confirm that the selected variant meets the required industrial temperature range specifications for your application environment before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG708CRU when an 8-to-1 multiplexing configuration is required within a compact surface-mount footprint. Ensure the system voltage aligns with the 1.8 V to 5.5 V single-supply range. Consider the 3 Ω on resistance and 14 ns switching speed for bandwidth and latency requirements. Verify that digital control signals are compatible with the specified TTL/CMOS input levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG708CRU belongs to the ADG708/ADG709 family of low-voltage CMOS analog multiplexers manufactured by Analog Devices. This series is designed for applications requiring low power dissipation and high switching speed. The CRU variant specifically denotes the commercial grade version housed in a 16-lead RU package, suitable for general-purpose industrial and consumer electronics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements within the same package and pinout include other ADG708 variants such as ADG708BRU or ADG708CRUZ. These alternatives share identical functional specifications but may differ in packaging format (tube vs. reel) or RoHS compliance status. Verify thermal and electrical equivalence before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

Can the ADG708CRU function as a demultiplexer?

Yes, the device can operate equally well as either a multiplexer or a demultiplexer due to its bidirectional switch design.

What is the purpose of the EN pin?

The EN (Enable) pin controls the device state. When driven low, it disables all channels, turning them off to reduce power consumption.

Does the ADG708CRU support automotive applications?

The standard ADG708CRU is not explicitly qualified for automotive use. Automotive-qualified versions are designated with the 'W' suffix, such as the ADW54008 models.
