MAX4781EGE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4781EGE is a high-speed, low-voltage CMOS analog switch and multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features an 8:1 multiplexer configuration housed in a 16-QFN (4x4) package. The device operates with a single supply voltage range of 2V to 12V or dual supplies of ±2V to ±6V. It provides a typical on-resistance of 1 Ohm and supports fast switching times, making it suitable for precision signal routing applications requiring low distortion and high bandwidth.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix requirements when ordering, as packaging options such as tape-and-reel may differ from tube configurations. Confirm RoHS compliance status and check current availability through authorized distributors, as stock levels for this component can vary. Ensure the selected variant matches the required operating temperature range and voltage specifications for the target application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8:1 signal routing solution is required within tight space constraints. The 16-QFN package offers thermal performance benefits compared to larger packages. Consider the 1 Ohm on-resistance for signal integrity needs. Verify that the input signal voltage levels remain within the safe operating area defined by the supply rails to prevent latch-up or damage during operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the Maxim Integrated family of high-speed analog switches and multiplexers. It complements other devices like the MAX4581 and MAX4780, offering higher channel density than quad switches while maintaining low on-resistance. The series is designed for applications demanding precise signal selection in data acquisition and communication systems.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the MAX4781EGE+T for reel-packaged versions. Cross-reference with MAX4581EGE+ if lower speed but higher resistance is acceptable. Verify pinout compatibility before replacing with generic 8:1 mux ICs.
