Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum power supply voltage for the DG9431?

The absolute maximum rating for the power supply range (V+ to GND) is +13 V, though typical operation is specified between +2.7 V and +5 V.

Does the DG9431 support dual supply operation?

No, the DG9431 is a single-supply device. Other models in the DG series, such as the DG441, support dual supplies.

How does the DG9431 prevent signal overlap during switching?

The device guarantees a break-before-make interval, ensuring the old connection is fully broken before the new one is established.
