Assembly of a data-acquisition system with its many parts (multiplexed, amplifiers, ADC, voltage reference, etc.) can be complex and expensive. The new Burr-Brown ADS7870 solves the problem with its 12-bit low-power CMOS dataacquisition system containing all parts mentioned, and extras. The space saving system is in a small (SSOP-28 surface-mount) plastic package. The price of the entire system is $3.90 (1K Qty).
