The ADG439FBRZ-REEL is a fault-protected CMOS analog multiplexer from Analog Devices, configured as a single-pole four-throw (SP4T) switch with a 4:1 multiplexer/demultiplexer circuit. It integrates two independent circuits, each offering 270 Ω typical on-state resistance with channel-to-channel matching of 8.1 Ω. The device provides robust fault protection, withstanding continuous overvoltage inputs from -40 V to +55 V, and ensures the output is clamped within the supply rails during fault conditions. Break-before-make switching action prevents momentary short circuits, and TTL/CMOS compatible logic inputs simplify interface design.
Key electrical characteristics include a maximum turn-on time of 230 ns and turn-off time of 130 ns, charge injection of 15 pC, and crosstalk of -93 dB at 100 kHz. The multiplexer operates from dual ±15 V supplies or a single 15 V supply, making it suitable for a wide range of analog signal routing applications. The device is housed in a 16-SOIC surface-mount package (0.154", 3.90mm width) and operates over the industrial temperature range of -40°C to 125°C.
Typical applications include data acquisition systems, industrial and process control, avionics test equipment, and signal routing between systems. The fault-protection feature ensures reliability in harsh environments where overvoltage conditions may occur.
