[quote user="Linnan Hu"]I am new to selection of MCUs, and now I need to choose a MCU with at least two 16-bit ADCs, two 12-bit DACs and 2 opamps.[/quote]Some parts in the MSP430FG series contain the required number of the stated peripherals - see the selection results http://www.ti.com/lsds/ti/microcontrollers_16-bit_32-bit/msp/products.page#!p121=ADC10 - 10ch;ADC10 - 12ch;ADC10 - 4ch;ADC10 - 5ch;ADC10 - 6ch;ADC10 - 8ch;ADC10 - 9ch;ADC12 - 10ch;ADC12 - 12ch;ADC12 - 14ch;ADC12 - 16ch;ADC12 - 20ch;ADC12 - 7ch;ADC12 - 8ch;ADC8 - 4ch;N/A;SigmaDelta16 - 1ch;SigmaDelta24 - 1ch;SigmaDelta24 - 2ch;SigmaDelta24 - 3ch;SigmaDelta24 - 4ch;SigmaDelta24 - 6ch;SigmaDelta24 - 7ch;Slope&~p1342=DAC;OpAmp As well as the peripherals, what do you need in terms of memory and processing speed?
