MAX4566EEE

Analog Switches - Special Purpose Overview

The MAX4566EEE is a low-voltage, bidirectional RF/Video switch IC manufactured by Analog Devices Inc./Maxim Integrated. It contains two dual SPST switches (one normally open, one normally closed) in a 16-pin QSOP package. The device operates with dual supplies from ±2.7V to ±6V or a single supply from +2.7V to +12V. Key electrical parameters include a maximum on-resistance of 60Ω at ±5V, a -3dB bandwidth of 350MHz, and off-isolation of -82dB at 10MHz. The industrial temperature range for the 'E' suffix is -40°C to +85°C.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm the exact package type and temperature rating. Ensure that the 'EEE' designation corresponds to the correct surface-mount variant and industrial grade specifications required for your design environment before finalizing procurement.

Analog Switches - Special Purpose Selection Notes

Select the MAX4566EEE when a dual configuration with both normally open and normally closed paths is required within a low-voltage system. Compare its 60Ω on-resistance and 350MHz bandwidth against other series members like the MAX4565 or MAX4567 to ensure the specific switch topology matches the circuit requirements.

Analog Switches - Special Purpose Part Context

This component belongs to the MAX4565/MAX4566/MAX4567 family of quad/dual, low-voltage, bidirectional RF/video switches. These devices are designed for switching signals from DC to 350MHz in 50Ω and 75Ω systems, offering rail-to-rail analog signal handling and low power consumption.

Analog Switches - Special Purpose FAQ

What is the difference between the MAX4566 and MAX4567?

The MAX4566 contains two dual SPST switches (one normally open, one normally closed), whereas the MAX4567 contains two single-pole/double-throw (SPDT) switches.

How does the T-switch architecture improve performance?

The T-switch construction uses two series CMOS switches with a third N-channel switch at the junction that shunts capacitively-coupled signals to ground when off, ensuring excellent high-frequency off-isolation and crosstalk.

Can the MAX4566 operate with a single supply?

Yes, it can operate with a single supply between +2.7V and +12V when the V- pin is connected to GND, although characteristics are optimized for ±5V dual supplies.
