MAX4660EUA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4660EUA+T is a single SPDT CMOS analog switch in an 8-pin µMAX-EP package. It features a maximum on-resistance of 25 Ω at ±15V supplies and supports continuous currents up to 150mA with peak handling of 200mA. The device operates from dual supplies of ±4.5V to ±20V or a single supply of +9V to +40V. Key electrical parameters include a -3dB bandwidth of 225MHz, charge injection of 1.5pC, and off-leakage current of 1nA max. It offers rail-to-rail signal handling, TTL/CMOS compatibility, and low power consumption of 3mW.

• Rail-to-rail analog signal switching across the full supply range
• Thermally enhanced exposed paddle package for improved heat dissipation

Analog Switches, Multiplexers, Demultiplexers Applications

• Relay replacement in high-speed switching applications
• Audio signal routing and audio systems
• Test equipment and communication systems
• xDSL modems and PBX/PABX systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the 'T' suffix indicates tape-and-reel packaging when sourcing this component. Confirm the exposed paddle (EP) variant matches the thermal requirements of the design. Ensure the ordering code corresponds to the specific Analog Devices/MAXIM Integrated manufacturing source to guarantee authenticity and compliance with RoHS standards.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4660EUA+T over the MAX4659 when higher continuous current capacity (150mA vs 75mA) is required. The exposed paddle package provides superior thermal performance compared to standard packages. Verify that the logic input voltage levels are compatible with the system's TTL or CMOS control signals before integration.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4659/MAX4660 family of high-current, 25Ω SPDT CMOS analog switches. It is pin-compatible with legacy parts like the DG419 and MAX319. The MAX4660 specifically distinguishes itself from the MAX4659 by offering doubled continuous current handling capabilities while maintaining similar on-resistance and switching characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible replacements include the MAX4659EUA+ and DG419. Note that the MAX4659 has lower continuous current ratings (75mA). Ensure any substitute part supports the required 150mA continuous load if current handling is critical to the application.
