MAX4711CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4711CSE+ is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features fault-protected inputs and rail-to-rail signal handling capabilities. The device operates from a single +2.7V to +11V supply or dual ±2.7V to ±5.5V supplies. Key electrical parameters include a maximum on-resistance of 25Ω at +25°C with a single supply, and 40Ω with dual supplies. Turn-on time is typically 125ns, while turn-off time is typically 80ns. The package is a 16-pin Narrow SOIC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE+' against the manufacturer's official ordering information to confirm the temperature range and RoHS compliance status. Ensure the narrow SOIC package dimensions match the target PCB footprint. Confirm availability through authorized distributors as stock levels fluctuate.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4711 variant specifically for normally closed (NC) configurations, distinguishing it from the MAX4712 (normally open) and MAX4713 (mixed). Evaluate the required on-resistance flatness and leakage currents against the application's signal integrity needs. Consider the power supply configuration when determining logic threshold compatibility.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX471x family of low-voltage analog switches. It shares pinouts with non-fault-protected counterparts but adds robust input protection. The C suffix denotes the commercial temperature range, while the E suffix indicates an extended range option.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX4712CSE+ and MAX4713CSE+. Verify that the substitute part number matches the required switch configuration (NO vs NC) before implementation.

Analog Switches, Multiplexers, Demultiplexers FAQ

Are all pins on the MAX4711 fault-protected?

No, only the NO_ or NC_ pins are fault-protected. The COM_ pins are not fault-protected and must be limited to the supply voltages to prevent damage.

What is the maximum fault voltage allowed on the inputs?

The NO_ and NC_ pins can withstand fault voltages up to ±12V relative to ground, even when the device power is off.

How does the device behave during a fault condition?

During a fault, the switch turns itself off, and the output is clamped to the same polarity supply as the input signal, preventing voltages beyond the supply rails from reaching downstream circuitry.
