Regarding NC pin, though it is described as NO CONNECT, there are instruction connecting with AGND.
Are they connected to an internal circuit? Are they used as a test terminal for production?
We do not typically disclose the internal nature of the NC pin because it may contain proprietary information regarding the nature of how we test our products. Please follow the datasheet recommendations otherwise we could not guarantee the part's performance.
We are looking into this. I'll get back to you soon.
