MAX4691EBE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4691EBE+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 digital inputs compatible with 1.8V logic at +3V and TTL at +5V. The device features rail-to-rail signal handling and a 16-bump UCSP package measuring 2mm x 2mm. Electrical characteristics include a maximum on-resistance of 70Ω at +2.7V, 35Ω at +5V, and 25Ω at ±4.5V dual supplies. Leakage current is specified at 20nA maximum at +85°C, with transition times of 90ns.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the marking code against official Analog Devices documentation. Confirm the presence of the lead-free suffix and tape-and-reel designation. Ensure the ordering information matches the specific temperature range and package type required for the application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when space constraints require a chip-scale package footprint. Verify that the system voltage aligns with the supported single or dual supply ranges. Consider the on-resistance specifications relative to the load requirements and ensure the logic levels match the controlling digital signals for proper switching operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4691–MAX4694 family of low-voltage analog switches. The MAX4691 variant specifically provides an 8:1 multiplexer configuration. Other family members include dual 4:1 muxes, triple SPDT, and quad SPDT switches, all sharing similar electrical characteristics and available in QFN, TQFN, and UCSP packages.
