Hi BS Khoo,
The newer generation version of the AD22050 is the AD22057. However, I would still recommend that you provide details of your application in case there is a more suitable part for you.
I am looking for device information on the AD22037Z, having misplaced my data sheets. I have just been told by the AD search engine that the nearest part was an AD22057! I am in the process of looking for replacements but so far nothing has really hit…
