MAX395EWG+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX395EWG+ is an 8-channel, serially controlled, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates with dual supplies from ±2.7V to ±8V or a single supply between +2.7V and +16V. The device features a maximum on-resistance of 100Ω, matched between channels to 5Ω max, with flatness of 10Ω max over the signal range. Turn-on and turn-off times are typically 400ns. It includes an asynchronous RESET input and supports SPI™/QSPI™ and Microwire™ interfaces. Operating temperature ranges from -40°C to +85°C in a 24-SOIC package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Serially controlled interface compatible with SPI™, QSPI™, and Microwire™ standards
• Eight individually controlled SPST switches with rail-to-rail signal handling capability
• Asynchronous RESET input for immediate switch opening and register clearing
• Pin-compatible with industry-standard MAX335 devices

Analog Switches, Multiplexers, Demultiplexers Applications

• Serial data-acquisition systems
• Industrial and process-systems control
• Avionics equipment
• Audio signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EWG+' corresponds to the industrial temperature range (-40°C to +85°C) and SOIC-24 package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure power supply rails match the specified operational limits to maintain electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when eight independently controllable analog switches are required within a compact surface-mount footprint. The serial interface reduces digital pin count compared to parallel alternatives. Verify that the 100Ω on-resistance meets system impedance requirements and that the voltage range aligns with available supply rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX395 family of low-voltage analog switches. It is electrically equivalent to two MAX391 quad switches controlled by a serial interface. The device shares pin compatibility with the MAX335, facilitating design upgrades or replacements in existing architectures without board layout changes.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX395CNG+ offers identical functionality in a PDIP-24 through-hole package. Other variants include MAX395CWG+ and MAX395MRG for different temperature ranges.
