MAX4660EUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4660EUA+ is a single SPDT CMOS analog switch in an 8-pin µMAX-EP package. It features a maximum on-resistance of 25Ω at ±15V supplies and supports continuous currents up to 150mA with peak handling of 200mA. The device operates on dual supplies from ±4.5V to ±20V or a single supply from +9V to +40V. Key electrical parameters include a -3dB bandwidth of 225MHz, charge injection of 1.5pC, off-leakage current of 1nA max, and crosstalk of -76dB at 1MHz. It offers rail-to-rail signal handling and TTL/CMOS logic compatibility.

• Audio signal routing and PBX/PABX system interconnects
• Test equipment and redundant backup system configurations
• xDSL modem signal path management

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix matches the required package type, as the MAX4660EUA+ specifically denotes the thermally enhanced 8-pin µMAX package with an exposed paddle. Confirm that the exposed paddle connection aligns with the design schematic, typically connecting to V+ or leaving unconnected per datasheet guidelines. Ensure the voltage ratings and current limits suit the target application loads.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4660EUA+ over the MAX4659 when higher continuous current handling (150mA vs 75mA) and thermal performance are required. The exposed paddle variant provides better thermal characteristics compared to standard packages. Verify that the supply voltage range fits within the ±4.5V to ±20V dual or +9V to +40V single supply constraints for optimal on-resistance performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4659/MAX4660 family of high-current, medium-voltage CMOS analog switches. The MAX4660 variant is distinguished by its ability to handle larger switch currents compared to the MAX4659. Both devices share similar pinouts and electrical characteristics but differ in current ratings and package thermal options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The device is pin-compatible with the DG419 and MAX319. When substituting, verify that the replacement part meets the 150mA continuous current requirement and 25Ω on-resistance specifications. Ensure the replacement package supports the necessary thermal dissipation if operating near maximum current limits.
