MAX4719EBC

Overview

The MAX4719EBC is a dual single-pole/double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.8V to +5.5V supply and features a low on-resistance of 20Ω maximum with 1.2Ω flatness and 0.4Ω channel matching at +3.0V. The device offers a -3dB bandwidth exceeding 300MHz, break-before-make switching with turn-on time under 80ns and turn-off time under 40ns at +2.7V. Digital logic inputs are compatible with +1.8V CMOS logic when powered between +2.7V and +3.6V. It provides rail-to-rail signal handling, high off-isolation of -55dB at 10MHz, low crosstalk of -80dB at 10MHz, and distortion of 0.03%. Leakage current is less than 0.5nA at +25°C.

Feature Summary

• Dual SPDT analog switch configuration with low on-resistance and high bandwidth for signal routing
• Single-supply operation from +1.8V to +5.5V with +1.8V CMOS logic compatibility
• Rail-to-rail signal handling capability with high off-isolation and low crosstalk

Applications

• Cell phones
• Battery-operated equipment
• Audio/video-signal routing
• Low-voltage data-acquisition systems
• Sample-and-hold circuits

Procurement Notes

Verify the specific suffix EBC corresponds to the UCSP package and commercial temperature range as defined in the official Maxim Integrated part numbering system. Confirm RoHS compliance status and lead times through authorized distributors, as availability may vary. Ensure the design supports the required +1.8V to +5.5V supply voltage and logic levels for proper interface.

Selection Notes

Select the MAX4719EBC for applications requiring high-speed signal switching in low-voltage environments. Its 300MHz bandwidth and low distortion make it suitable for audio and video routing. The +1.8V logic compatibility simplifies integration with modern microcontrollers. Consider the UCSP package size for space-constrained designs in portable devices.
