MAX4658EUA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4658EUA+ is a high-speed, low-voltage analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features a single SPDT configuration housed in an 8-pin uMAX or uSOP package with an exposed pad for thermal management. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V. Key electrical parameters include a maximum on-resistance of 4 Ohms, a typical on-resistance flatness of 0.1 Ohm, and a bandwidth of 250 MHz. Switching times are characterized by a maximum turn-on time of 15 ns and a maximum turn-off time of 5 ns. The component supports a continuous current of 50 mA and draws a maximum supply current of 1 uA. It functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix (e.g., E, UE, ET) to confirm the exact package type and tape/reel configuration required for your assembly process. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure the ordering part number matches the desired lead-free and halogen-free specifications mandated by your project requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high bandwidth are critical for signal fidelity in low-voltage environments. Compare against the MAX4657 and MAX4659 if dual-supply operation or different pin configurations are needed. Consider the exposed pad requirement for thermal dissipation during PCB layout design to ensure reliable performance under continuous load conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4658 belongs to the Maxim Integrated family of high-speed CMOS analog switches designed for portable and battery-operated applications. It complements other devices like the MAX4657 and MAX4659, offering a balance between speed, power consumption, and on-resistance. The uMAX package provides a small footprint suitable for space-constrained designs common in modern consumer electronics and industrial control systems.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4657EUA+ serves as a direct functional substitute with identical pinout and electrical characteristics but utilizes a standard SOIC-8 package without the exposed thermal pad. Verify thermal requirements and PCB land pattern compatibility when substituting between these package variants.
