Multichannel AD8332/AD8334 board design for ultrasonic imaging

Hi MrEngineer1990,

We have a page that is all about Medical Ultrasound applications at Analog Devices that you might want to take a look. The link of the page is Medical Ultrasound | Analog Devices.

One of the featured products on the page is the AD8334, which I believe could be of particular interest to you. But if that doesn't quite fit your needs, you can always check out the other options that are most similar to what you're looking for in your applications.

Thank you!

Best regards,

Mae

Hi Mae, I am aware of all the product offerings. As I said in my post, I've identified the AD8334 as the best one. The challenge I have is I don't have the expertise to design a board with several of this chips, in order to make a multichannel array. Do you have any suggestions?

Hi MrEngineer1990,

Analog signal processing components are key elements in determining the overall system performance for your ultrasonic application. For starters, the link attached will help you narrow down and select the right component for your design requirements.

As your preferred amplifier is AD8334 and as this is also one of the options in the attached link, you may use the signal chain design in the link as reference. 

If you scroll down a little on the website, you will see this:

This signal chain block is an interactive design for ultrasound application. For example you click on the VGA block, a list of suggested VGAs will appear. Then if you click on the other components, for example the "amp", a list of suggested amplifiers that are best for ultrasound applications will appear. 

There are major trade-offs to be considered when designing ultrasound front-end circuits. We have an article that discusses requirements and trade-offs for Ultrasonic Design. I suggest you take a read on this Analog Dialogue: How Ultrasound System Considerations Influence Front-End Component Choice.

Hopefully this gives you a kickstart on where to look at and how to select the best components.

Let me know if you have any questions.

Best regards,

Mae
