Seems an old post, but based on the reference images they supplied the ADC performance is greatly improved over the utterly dire ones I've experienced on the Arduino.

I don't know if anyone suggested this yet Bill, but my lorks, the ADCs on these fellas are noisy for sensitive measurements (as I learned when I got a cheap digital scope from China recently). This thing is so bad it's almost unusable and it's entirely down to ADC noise!

So is it the LPC1343 you are interested in, or an improved ADC?  Because the spec sheet for the LPC1343 shows that it also has a 10-bit ADC, the same resolution as the Arduino, although it probably is faster as its clock speed is a lot higher.  Otherwise, I'm puzzled as to what improvement you'd see here, unless it has a lower noise floor?

The ESP-32 has a 12-bit ADC and is faster than both chips.

Perhaps I'm missing the point here, so please feel free to enlighten me!
