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, featuring rail-to-rail signal handling and a maximum leakage current of 1nA. The device utilizes 1.8V logic-compatible digital inputs at +3V operation. Key electrical parameters include a maximum on-resistance of 70Ω at +2.7V supply, 35Ω at +5V supply, and 25Ω at ±4.5V dual supplies. It offers guaranteed channel matching of 5Ω max at +2.7V and 3Ω max at ±4.5V, with a maximum on-resistance flatness of 3.5Ω at ±4.5V. The component supports fast transition times of 90ns and provides high off-isolation of -88dB at 100kHz.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the package type matches the specific design requirement, as the MAX4691 family includes UCSP, QFN-EP, and TQFN-EP options. Confirm that the ordering suffix corresponds to the desired tape-and-reel quantity if applicable. Ensure the selected variant meets the thermal dissipation needs of the target PCB layout. Cross-reference the datasheet revision to confirm pinout consistency before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexing function is required in a compact form factor. The QFN-EP package is suitable for designs prioritizing thermal performance and board space efficiency over the UCSP option. Verify that the system voltage aligns with the guaranteed on-resistance specifications, as resistance increases significantly at lower supply voltages below 3V.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4691–MAX4694 family of low-voltage analog switches manufactured by Analog Devices / Maxim Integrated. The family differentiates by configuration, offering 8:1 mux, dual 4:1 mux, triple SPDT, and quad SPDT variants. The MAX4691 specifically provides the single 8-channel multiplexer topology within this series.
