MAX391ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX391ESE is a precision, quad, single-pole single-throw (SPST) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. It operates with a single supply voltage ranging from 3 V to 15 V or dual supplies of ±3 V to ±8 V. The device features a maximum on-resistance of 35 Ohms and low power consumption with a maximum supply current of 1 uA. It is housed in a 16-pin SOIC-Narrow package and supports surface-mount installation. The component is rated for an operating temperature range from 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Precision SPST switching configuration with four independent channels
• Low power operation suitable for battery-powered applications
• High off-isolation performance for signal integrity

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in data acquisition systems
• Multiplexing sensor inputs
• Audio signal path switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the commercial temperature grade (0°C to +70°C) and 'SE' denotes the SOIC-Narrow package. Confirm RoHS compliance status as '+T' variants are explicitly listed as compliant in distributor records, whereas standard suffixes may vary. Ensure the source document matches the exact part number to avoid confusion with the discontinued MAX391EPE DIP version.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST switch with low on-resistance is required for single or dual supply environments. Compare against the MAX392 series if normally-open logic is preferred over the MAX391's default configuration. Verify that the 35 Ohm on-resistance meets the application's signal loss requirements and that the 130 ns turn-on time is sufficient for the target bandwidth.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX391 belongs to the Maxim Integrated precision analog switch family, designed for high-performance signal switching. It shares architectural similarities with the MAX392 and MAX393, differing primarily in channel count and internal logic polarity. This specific model represents the quad SPST variant in a surface-mount package, distinct from the through-hole DIP versions like the MAX391EPE.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX392ESE+T is a functional substitute within the same package offering different logical polarity. For pin-compatible alternatives, consider the ADG441BNZ from Analog Devices, which provides similar SPST functionality in a comparable form factor.
