MAX4732EUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4732EUA+ is a dual single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2.0V to +11V supply and handles rail-to-rail analog signals. The device features two normally closed (NC) switches with a maximum on-resistance of 50Ω at +3V and 25Ω at +5V. Key electrical parameters include an off-leakage current of less than 0.1nA, a quiescent power consumption of typically 0.5nW, and a -108dB crosstalk specification at 1MHz. It is housed in an 8-pin µMAX package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual SPST configuration with normally closed contacts for signal routing
• Rail-to-rail analog signal handling capability across the full supply voltage range
• Ultra-low leakage current and negligible quiescent power consumption
• TTL/CMOS logic compatibility for direct interface with digital control systems

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-powered portable electronic systems
• Audio and video signal routing matrices
• Low-voltage data-acquisition front ends
• Cellular phone and PDA circuitry
• Communications equipment signal paths

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EUA+' corresponds to the 8-pin µMAX package variant when sourcing components. Confirm that the procurement documentation explicitly lists the -40°C to +85°C industrial temperature range. Ensure compliance with RoHS directives as indicated by the '+' suffix designation in official manufacturer catalogs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual normally closed analog switch is required for low-power applications. The 50Ω on-resistance at +3V makes it suitable for moderate impedance signal paths. Consider the 8-pin µMAX package for surface-mount assembly where board space allows slightly larger footprints compared to UCSP alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4731/MAX4732/MAX4733 family of low-voltage analog switches. While the MAX4731 offers normally open contacts and the MAX4733 provides mixed NO/NC configurations, the MAX4732 specifically provides dual normally closed functionality. All variants share identical electrical characteristics and package options within the series.
