MAX4691EGE-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4691EGE-T is a low-voltage CMOS analog integrated circuit configured as an 8-channel multiplexer. It operates from a single +2V to +11V supply or dual ±2V to ±5.5V supplies, with the latter configuration supporting rail-to-rail signal handling. The device features guaranteed on-resistance of 70Ω (max) at +2.7V and 35Ω (max) at +5V, alongside low leakage currents of 20nA (max) at +85°C. Digital inputs are compatible with 1.8V logic at +3V and TTL at +5V. Packaged in a 16-pin QFN-EP, it ensures break-before-make switching and high off-isolation.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel status. Ensure the component meets lead-free and RoHS compliance requirements if mandated by your assembly process. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring an 8-channel multiplexer in a compact footprint. Verify that the system voltage aligns with the single-supply (+2V to +11V) or dual-supply (±2V to ±5.5V) operational limits. Confirm that the digital control logic levels match the 1.8V or TTL compatibility specifications provided for the respective supply voltages.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4691–MAX4694 family of low-voltage analog switches manufactured by Analog Devices/Maxim Integrated. While the MAX4691 specifically provides an 8:1 multiplexer function, related variants in the series offer dual 4:1 muxes, triple SPDT, or quad SPDT configurations within similar package options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4692, MAX4693, and MAX4694, though these provide different switch topologies. For identical 8-channel multiplexer functionality, verify availability of other package variants such as MAX4691EBE+T or MAX4691ETE+T.
