MAX369EWN+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX369EWN+ is a dual SP4T analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features two independent 4:1 multiplexer circuits housed in an 18-SOIC package. The device operates on dual supplies ranging from ±4.5V to ±18V. Key electrical parameters include a maximum on-resistance of 1.8 kΩ, channel-to-channel matching of 180 Ω, and a maximum charge injection of 55 pC. Switching times are specified at 1.5 µs for turn-on and 1 µs for turn-off. Off-state leakage current is limited to 5 nA, with off-state capacitances of 5 pF and 12 pF. It supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix designation carefully, as the base model MAX369 may have different availability or compliance status than the MAX369EWN+. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as historical data indicates potential variations within the product line. Ensure the component meets all environmental regulations required for your specific deployment region before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual isolated signal paths are required with moderate on-resistance values. The wide dual-supply range allows compatibility with various analog signal levels. Consider the 18-SOIC package constraints for PCB layout. Verify that the 1.8 kΩ on-resistance meets the application's voltage drop requirements. Check if the switching speed specifications align with the system timing constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX369 belongs to the Maxim Integrated analog switch family, designed for general-purpose signal routing. It complements other devices like the MAX368, which offers fault protection but typically in single-channel configurations. The EWN suffix denotes the specific industrial temperature grade and SOIC packaging variant within the broader MAX369 product series.
