I have a project where i need to build a data logger which will log temperature from 8 sources and send it via uart to the PC. The temperature sensor will be a thermocouple.
But all AVRs are 10bit. So I cannot use the internal ADC of the AVR chips.
I am looking for at least 12 Bits and 8 Channels preferably on an I2C bus. Can someone suggest me a part number??
