MAX369CWN

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX369CWN is a dual-channel analog switch manufactured by Analog Devices Inc./Maxim Integrated, housed in an 18-SOIC surface-mount package. It functions as two independent SP4T switches or a single 4:1 multiplexer/demultiplexer circuit. The device supports dual supply voltages ranging from ±4.5V to ±18V. Key electrical specifications include a maximum on-resistance of 1.8 kΩ and a channel-to-channel matching of 180 Ω. Switching times are specified with a maximum Ton of 1.5 µs and Toff of 1 µs. Leakage current is limited to 5 nA maximum, while charge injection is 55 pC. Operating temperature range extends from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for alternative sources if immediate availability is critical, noting that stock levels are likely limited. Validate package integrity upon receipt to ensure suitability for surface-mount assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SP4T switching with high voltage capability is required. Ensure the 1.8 kΩ on-resistance meets system impedance requirements. Verify that the 1.5 µs switching speed is sufficient for the application timing constraints. Consider the 18-SOIC package dimensions for PCB layout compatibility. Evaluate thermal performance within the -40°C to +85°C operating range.

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 in the series offering different resistance values or pin counts. The CWN suffix indicates commercial temperature range and SOIC packaging.
