MAX4611ESD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4611ESD+ is a quad, low-voltage, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed (NC) switches operating from a single +2V to +12V supply. The device guarantees an on-resistance of 100Ω max at +5V and 46Ω max at +12V, with channel matching within 4Ω max and flatness over the signal range at 18Ω max. Off-leakage current is limited to 1nA at +25°C and 2nA at +85°C. It provides 2kV ESD protection per Method 3015.7 and operates in the -40°C to +85°C temperature range.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official datasheet specifications for electrical parameters and package dimensions. Confirm that the ordering suffix corresponds to the required temperature range and packaging format. Ensure compliance with RoHS standards as indicated by the plus sign in the part number. Cross-reference pin configurations to match design requirements before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when normally closed switching states are required for signal paths. Evaluate the on-resistance limits against the specific supply voltage used in the application circuit. Consider the TTL/CMOS logic compatibility for direct interfacing with standard digital controllers. Verify that the maximum supply voltage does not exceed the absolute ratings during operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage CMOS analog switches. While the MAX4610 offers normally open switches and the MAX4612 combines both types, the MAX4611 specifically provides four normally closed channels. All variants share similar electrical characteristics and pinouts, differing primarily in their default switch states.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4611CSD+ serves as a commercial grade replacement within the same package type.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the switches in the MAX4611?

The MAX4611 contains four normally closed (NC) switches, meaning they conduct current by default until a high logic level is applied to the input.

How does the on-resistance vary with supply voltage?

On-resistance decreases as supply voltage increases; it is guaranteed at 100Ω max at +5V and 46Ω max at +12V.

Is the MAX4611 compatible with standard logic families?

Yes, the digital inputs have thresholds ensuring TTL/CMOS-logic compatibility when using a single +5V supply.
