These functions are segmented onto two monolithic chips—an analog signal pro- cessor and a digital controller. Both chips are contained within the AD package. The AD employs a successive-approximation technique to determine the value of the analog input voltage. However, in- stead of the traditional laser-trimmed resistor-ladder approach, this device uses a capacitor-array, charge redistribution tech- nique. Binary-weighted capacitors subdivide the input sample to perform the actual analog-to-digital conversion. The capacitor array eliminates variation in the linearity of the device due to temperature-induced mismatches of resistor values.
