MAX395EAG

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX395EAG+ is an eight-channel, serially controlled, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single supply voltage ranging from 2.7V to 16V or dual supplies from ±2.7V to ±8V. The device features a maximum on-resistance of 100Ω with channel-to-channel matching of 5Ω max and flatness of 10Ω max over the signal range. Switching times are limited to 400ns for both turn-on and turn-off periods. It utilizes a SPI/QSPI/Microwire-compatible serial interface for control and includes an asynchronous RESET input. The component is housed in a 24-pin SSOP package and supports operation within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Serially controlled architecture utilizing SPI, QSPI, or Microwire-compatible interfaces for efficient pin count management.
• Rail-to-rail signal handling capability allowing full voltage swing across the specified supply ranges.

Analog Switches, Multiplexers, Demultiplexers Applications

• Serial data-acquisition systems requiring multi-channel signal routing.
• Avionics equipment needing reliable low-voltage switching solutions.
• Audio signal routing matrices for professional audio processing.
• Industrial and process control systems for sensor signal selection.
• Automated test equipment (ATE) for flexible signal path configuration.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EAG+' against the manufacturer's current part numbering system to confirm package type and RoHS compliance status. Cross-reference the Mouser number 700-MAX395EAG for availability checks. Ensure the ordering documentation explicitly states the SSOP-24 package variant. Confirm lead times directly with authorized distributors as stock levels fluctuate. Validate that the component meets the required environmental specifications for the intended deployment zone.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing systems requiring eight independently controllable analog paths with minimal control lines. The low power consumption of 20µA makes it suitable for battery-operated applications. Ensure the signal amplitude remains within the ±5V limit if maintaining the 100Ω on-resistance specification is critical. Consider the 400ns switching speed for timing constraints in high-speed multiplexing scenarios. Verify compatibility with the host microcontroller's serial protocol standards before integration.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX395 belongs to the Maxim Integrated family of low-voltage analog switches designed for space-constrained applications. It serves as a pin-compatible alternative to industry-standard devices like the MAX335, facilitating direct upgrades in existing designs. The series emphasizes low power and high density, making it a common choice for portable electronics and compact industrial modules where board real estate is limited.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX395CNG+ and MAX395EWG+ are verified pin-compatible alternatives within the same product family. These variants offer identical electrical performance but differ in packaging, providing DIP and SOIC options respectively. Verify that the thermal characteristics and physical footprint of the replacement package align with the PCB design constraints before substitution.
