Always request the full NDA-protected datasheet from your FAE (Field Applications Engineer). If they hesitate, ask for "Appendix J – Timing and Hold Exceptions." That is the test they expect you to fail. my 9892 datasheet exclusive
| Register | Bit | Function | Exclusive Note | | :--- | :--- | :--- | :--- | | 0x0A | 4 | ADC dither enable | Increases ENOB from 20.1 to 21.3 bits at the cost of 5% more current. | | 0x0F | 7 | Fast settling mode | Reduces settling time to 40 µs but increases noise floor. Use only for DC measurements. | | 0x12 | 0:2 | Output driver strength | Default is '000' (weak). Set to '101' for driving long traces >10 cm. | | 0x1C | 3 | Internal reference bypass | Use only if you supply external REF. Prevents contention. | // My 9892 Exclusive Init Sequence – Do

Now go build something extraordinary with your 9892. Have a specific question about the 9892 that even the exclusive datasheet didn’t answer? Leave a comment below or reach out to our engineering forum. And if you found a hidden feature of your own, share it—exclusives are better when they are shared.
The 9892 is not just another ADC or processor. It is a precision instrument. And like any fine instrument, its performance depends entirely on how well you understand its soul. The public datasheet gives you the skeleton; the gives you the nervous system.
If you have landed on this page, you likely possess this component—or are considering integrating it into your next flagship project. But raw pinouts and timing diagrams are not enough. You need context, application notes, and the "exclusive" insider knowledge that separates a working prototype from a production-ready masterpiece.
