ADG508FBRUZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG508FBRUZ is an 8-channel analog multiplexer in a 16-lead TSSOP package. It supports dual supplies from ±5 V to ±22 V (9 V to 44 V single supply). The device features fault protection for inputs between −40 V and +55 V. Maximum on-resistance is 390 Ω at ±15 V, with a maximum switching time of 230 ns and off-time of 130 ns. Leakage current is limited to 2 μA during faults or power-off states. Operating temperature range is −40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault protection withstands continuous overvoltages from −40 V to +55 V regardless of power state
• Break-before-make switching prevents momentary shorting of input signals
• Trench isolation eliminates latch-up susceptibility

Analog Switches, Multiplexers, Demultiplexers Applications

• Existing multiplexer applications requiring fault protection
• New designs requiring multiplexer functions
• Sensor signal routing where source protection is required

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix RU-16 corresponds to the 16-lead TSSOP package variant. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the component matches the B version specifications for industrial temperature ranges. Cross-reference pinout details against the official datasheet before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when 8 channels are required with high-voltage fault tolerance up to +55 V. The TSSOP package suits surface-mount designs needing compact footprints. Verify that the 390 Ω maximum on-resistance meets system loss requirements. Consider the ADG509F if differential channel configurations are needed instead.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG508FBRUZ belongs to the ADG508F/ADG509F series of CMOS analog multiplexers. It provides eight single-ended channels controlled by three binary address lines. The BRUZ suffix indicates the 16-lead Thin Shrink Small Outline Package (RU-16) option compliant with JEDEC standards.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG508FBRNZ serves as a direct replacement using the SOIC-16 package. The ADG508FBRWZ offers the same functionality in the SOIC-Wide package. Verify pin compatibility and thermal characteristics when substituting these variants.
