MAX350EWN

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX350EWN+ is a dual 4-channel serially controlled analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates with single supplies from +2.7V to +16V or dual supplies from ±2.7V to ±8V. The device features bidirectional signal paths with a maximum on-resistance of 100Ω and an off-leakage current of 0.1nA at +25°C. It utilizes an SPI/QSPI/MICROWIRE-compatible serial interface for control. The component is housed in an 18-pin Wide SO package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended industrial temperature range (-40°C to +85°C) compared to commercial variants. Confirm the 'W' suffix corresponds to the Wide SO-18 package dimensions. Ensure the '+' suffix denotes RoHS compliance status as per manufacturer specifications before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4-channel configuration is required rather than a single 8-channel layout. Verify that the supply voltage requirements align with the specified single or dual supply ranges. Consider the serial interface timing constraints if interfacing with high-speed digital controllers.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX349/MAX350 family of low-voltage multiplexers. The MAX350 variant specifically provides two independent 4-to-1 multiplexer channels within a single integrated circuit. This family is designed for applications requiring precise analog signal routing with minimal power consumption.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX349CWE+ serves as a functional alternative if a single 8-channel multiplexer configuration is acceptable instead of the dual 4-channel setup provided by the MAX350.
