For whom are Evaluation Board for Operational Amplifier

Hello,

there are many different Evaluation Boards for Operational Amplifier.

For example
Evaluation Board for the ADA4522-2
Evaluation Board for the ADA4625-2
Evaluating Board for the ADA4523-1

My question is, what is the target group.

Is this for hobby people that can not design a PCB Board for the Operational Amplifier?
Or is this for professional?

But if a professional want try a Operational Amplifier, is it not better to design a test PCB for the specific requirement?

Best regards

Building a board can end up costing more than buying it off the shelf (time spent in layout and procurement add up quickly). So they are useful before you start designing. Also useful when there is some issue with an assembled product just to eliminate variables (is it the larger designs power supply, or some coupled noise?) by testing the part in a simpler situation.

Hi,
The semiconductor manufacturers have gone to a lot of trouble to design the evaluation boards so that will give 'datasheet' performance. It may have taken a few revisions to achieve this.

In addition to being used to evaluate the parts, in this case high performance op-amps, in a typical application. They are also reference designs that can be copied into products.

And this is probably the reason I buy them even as a hobbyist.  There are sometimes design issues that might be incorporated in the evaluation board that aren't well described in the datasheet.

TI is especially good about having evaluation boards.  Sometimes they are just fun:

The target group is the electronic design engineers, not the hobbyist.

Many devices have their particularities and subtleties that might not be well understood at first, so a reference design and a proper PCB layout are of great help.

It will be a huge waste of time (multiplied with the number of designers) if each design engineer will start to experiment with each product, not knowing what to blame when something does not meet the expectations.
