The ADuC816 is a complete smart transducer front-end, integratingtwo high-resolution sigma-delta ADCs, an 8-bit MCU,and program/data Flash/EE Memory on a single chip. This lowpower device accepts low-level signals directly from a transducer.The two independent ADCs (Primary and Auxiliary) include atemperature sensor and a PGA (allowing direct measurement oflow-level signals). The ADCs with on-chip digital filtering areintended for the measurement of wide dynamic range, lowfrequency signals, such as those in weigh scale, strain gauge,pressure transducer, or temperature measurement
