Recently, I am an electronics a student of grade 2, applied to the design of course, I want to do, a temperature sensor AD590 to heat, followed by amplifying circuit, ADC chip to do now want to find a modulus conversion, and then draw a board is done as far as possible and practical, has been used before on the single chip microcomputer of built-in ADC, so the selection of the chip is not understand, is changed a few DA, ADC chip, 12, 16 is ok, but still want to a little bit more simple and the precision is higher, please recommend everyone familiar with the bosses, sincerely hope can get everybody's help,

With the help of a selection of TI's official website, also can apply for samples

AD590 is 4-20 ma output chip, the current into a voltage with resistance, with AD MCU to temperature measurement is relatively reasonable solution,
