I want to evaluate AD9237 but evaluation board does not exist.I will try to evaluate AD9237 using a compatible AD9235 evaluation board.So, I confirmed that some pin functions are different, but it is OK to replace
AD2935 from AD9237, or is it…
We check power consumption of AD9237-40 both power scaling enable and disable .Datasheet figure 43 and 44 describle only power consumption by 10MSPS at power scaling disable and enable.Please let me knoe about power consumption when we use AD9237…
Please support this thread ?
We attach description of datasheet and my understanding about reference configuration
Is below understanding correct ?
Please let me know yoru advice.
Thank you for using the AD9237.
Applying 2.5V to the MODE2 pin will not damage the part as long as the AD9237 is powered up before the 2.5V source.
From your testing, you have about 100mV margin at 2.5V. To increase your margin, you…
The AD9280 is much older ADC thus really is not recommended. Since you are simply buying an eval board, I would consider a higher resolution ADC like the 12-bit AD9237. The AD9237 is a monolithic, single 3 V supply, 12-bit, 20/40/65 MSPS Analog…
Thanks for the information,
Obviously I overlooked this figure.
Upgrading to AD9237 is however no option to me due to nontechnical reasons.
However an external Reference seems useful.
The AD9225 is one of the 1st generation 12-bit CMOS ADC's released in the late 1990's. As you state, it does not include a PWDN pin which exists on future generations of this product family. No additional delay is required (other than…
You may want to check the ADI website and do a parametric search to filter the product display base form your recommended specification.
Here are some ADCs that might help you start with, kindly see attched file.
Choosing a high sample rate converter will definitely aide in reducing the cost and complexity of the anti-aliasing filter (AAF). Next, if possible, choose a 20MHz BW to be within baseband at Fs/4 or greater, this will push the harmonics…
