Analog devices offer a wide range of multiplexers. These devices come in a variety of packages that can best fit the needs of a customer’s applications. But deciding the best multiplexer from several available choices is a difficult task. A self-explaining buying guide works wonders in the selection process, and the below-mentioned information is like this guide.
Supply voltage parameters
The performance of the analog multiplexer depends on the supply voltage. A variety of supply voltage is available for these devices. Low voltage multiplexers offer better performance than the high voltage ones. Single and dual supply options are also available with these devices.
Performance factors of analog multiplexers
The first performance measure is the on-resistance that occurs between the source and the drain. The lower the on-resistance, the lower will be the distortion. The second is the capacitance, which is when low works well. Then check for the leakage factor, which should also below so that fewer losses occur. It will be in your device’s favor if you check the availability of the required bandwidth. Check on crosstalk is also an essential factor.
Power-off protection feature
This feature means that the device will auto-shut in case of the absence of a power supply. The damaging current won’t flow in the multiplexer circuit and will prevent any loss to the sensitive equipment. Also, check for the availability of overload voltage protection. If there comes a situation where the analog input exceeds the supply, then one of the switches of the multiplexer will go off and prevent any damage that could have been caused by the exceeding supply. Channel protectors are also required to protect the sensitive elements of the device.
