ADG508FBRNZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG508FBRNZ-REEL7 is an 8-channel analog multiplexer from the ADG508F series, manufactured by Analog Devices Inc. It features a 16-lead SOIC_N (SOIC-16) package and operates within an industrial temperature range of -40°C to +85°C. The device supports dual supply voltages between 10.8 V and 16.5 V, with a typical operating voltage of 15 V. Key electrical parameters include a maximum on-resistance of 390 Ω, a maximum power dissipation of 3.3 mW, and a maximum supply current of 1 μA. Switching performance is defined by a maximum turn-on time of 230 ns and a maximum turn-off time of 130 ns.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Provides fault protection against continuous overvoltage inputs ranging from −40 V to +55 V, ensuring device and signal source safety during power loss or overvoltage events.
• Utilizes break-before-make switching construction to prevent momentary shorting of input signals during channel transitions.
• Incorporates latch-up proof construction via dielectric trench isolation that separates p-channel and n-channel MOSFETs.

Analog Switches, Multiplexers, Demultiplexers Applications

• Existing multiplexer applications requiring fault protection capabilities
• New designs necessitating standard multiplexer functions
• Data acquisition systems requiring robust analog signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration, as indicated by the REEL7 designation in the part number. Ensure compatibility with the 16-lead SOIC_N footprint during PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to integration into production assemblies.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high-voltage fault tolerance and low leakage currents. Compare the 390 Ω maximum on-resistance against system requirements for signal integrity. Consider the 16-lead SOIC package dimensions for space-constrained designs. Evaluate the ±15 V dual supply operation against available power rails in the target circuit architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG508F/ADG509F family of CMOS analog multiplexers. The ADG508F variant specifically provides eight single-ended channels, whereas the ADG509F offers four differential channels. Both share identical fault protection mechanisms and pinout configurations, differing primarily in channel count and type.
