The MAX1168BEEG+ is a 16-bit SAR ADC with 8 single-ended inputs and SPI interface, sampling at 200k samples per second.
It's ROHS3 compliant, which clears the EU and California regulatory gates.
The digital supply accepts 2.7V to 5.25V, so a 3.3V rail works fine for the SPI interface. The analog supply must be 5V — that rail powers the SAR core and the input mux.
Yes, it has an internal reference, and it also accepts an external reference. You can use the internal one for a simpler BOM or switch to an external precision reference for tighter accuracy over temperature.
Within the same Maxim family, the MAX1167 is a 16-bit SAR ADC with a similar feature set but a different channel count or interface variant. Check the pinout against your layout before swapping — the MAX1168BEEG+ has 8 single-ended inputs and an SPI interface in a 24-QSOP package.
