Look at this one from Analog Devices, it is in 6x6mm package (I've just received the samples):

Hi,
if you are looking for the best analog features in a small package, no doubt, ADI is always in the picture.
If the analog features are not your primary concern, the 7023 offers max 20 I/O while it needs more than 7 times the real estate on the board. Although I do not know the pricing for the LPC1102 it might be between $1-$2 @ 1k, the ADI device is $5 from Digikey @ 1k. The 7023 is slower, needs an external oscillator for using the UART (3% accuracy versus 1% on the LPC), has an ARM7 instead of a Cortex-M0..
Apples compared to Oranges and again, if it comes down to ADC and DAC, the aduc7023 is definitely better, everything else....
After checking the LPC1300 and LPC1700 families I could see that the aduc7023 fits nicely in between the NXP offering in package size and code memory. The LPC1752 for example costs less, reference 1k pricing @ Digikey. It also has a 12-bit ADC, double the I/O, 3x performance, double the memory but it also needs 4 times the real estate on the board.
So if you need it small but not tiny and the 12-bit ADC and DAC is your focus, you are dead on.

by the way, there is an even smaller MCU from Atmel, an AVR with 4mm2 footprint but this one plays in a different league all together.
