Digital temperature compensation
demand compactness lower power dissipation, circuits portable devices being manufactured individual chips. particular, during manufacture modular devices comprised several individual discrete devices, significant time effort must devoted adjusting temperature characteristic each discrete device individually, addition, demand power consumption increasing. response these requirements, Toshiba have developed digital temperature compensation Toshiba have implemented this device completely CMOS, obviating need combinations individual electronic components, such thermistors resistors, case Weight: 0.02 (typ.) previously. digital temperature compensation incorporates temperature sensor, E2PROM converter. accurate within meet demand compactness, comes World's smallest flattest 16-pin package (US16).
