redistribution and the three least significant by a resistor array.
I've not seen it stared directly but here is my evidence from SLAU049:
- There is a SAR (successive approximation register) shown in figure 15-2.
- From 15.2.1: "It is important to note that the 3LSBs of the conversion are
- From 15.3.2: "During sampling, the analog input signal is applied to the
internal capacitor array of the A/D core."
- From 15.6: "Thirteen conversion clocks (ADC12CLK) are required to complete

Of course we know - it's a SAR type. If you look at the schematic
that's shown in the User's Guide, right under the block that
says "12-bit A/D Converter Core", there's a block that says 12-bit
SAR. We probably don't advertise the type that much because non-
analog engineers don't always understand (or care about) the
