MAX4691ETE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4691ETE+T is a low-voltage CMOS analog switch configured as an 8-channel multiplexer in a 16-pin TQFN-EP package. It operates from a single +2V to +11V supply or dual ±2V to ±5.5V supplies. Key electrical parameters include a maximum on-resistance of 70Ω at +2.7V, 35Ω at +5V, and 25Ω at ±4.5V. The device features a maximum on-resistance flatness of 3.5Ω and channel matching of 3Ω under dual supplies. Switching performance includes a transition time of 90ns and leakage currents as low as 1nA. Digital inputs are compatible with 1.8V logic at +3V and TTL at +5V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix ETE+T corresponds to the 16-pin TQFN-EP package with tape and reel packaging. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering code matches the exact temperature range and pin configuration required for the design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8:1 multiplexing function is required in a compact surface-mount form factor. Consider the TQFN-EP package for improved thermal dissipation compared to UCSP variants. Verify that the required on-resistance and switching speed meet the system specifications under the intended supply voltage conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4691–MAX4694 family of low-voltage analog switches. The MAX4691 specifically provides an 8-channel multiplexer configuration. Other family members include dual 4:1 muxes, triple SPDTs, and quad SPDTs, all sharing similar low-voltage operation and logic compatibility characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements within the same series include MAX4691EGE+ (QFN) and MAX4691EBE+T (UCSP). Verify pinout compatibility and package dimensions before substitution. Ensure the alternative package meets the thermal and mechanical requirements of the application.
