MAX4702ETE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4702ETE+T is a low-voltage, single-supply CMOS analog switch featuring four independent single-pole/double-throw (SPDT) channels. It operates from a +1.8V to +5.5V power supply and includes a dedicated logic power supply input for optimized control thresholds. The device provides rail-to-rail signal handling with a maximum on-resistance of 75Ω at +3V and 40Ω at +5V. Key electrical parameters include a 250MHz -3dB bandwidth, switching speeds of 35ns turn-on and 20ns turn-off, and leakage currents as low as 1nA. It is housed in a compact 16-pin TQFN package.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4702 handle logic input thresholds?

The MAX4702 features a dedicated logic power supply input (VL) that allows for lower logic input thresholds, enabling operation with logic levels as low as 1.0V.

What is the guaranteed switching behavior of the MAX4702?

The device guarantees a break-before-make switching action, ensuring that one channel opens before another closes to prevent signal shorting.

Can the MAX4702 handle signals ranging from ground to the positive supply?

Yes, the switches feature rail-to-rail signal handling, allowing analog signals to pass through the entire supply voltage range with minimal change in on-resistance.
