AD7747 Pdf资料

应用功能： 24-Bit Capacitance-to-Digital Converter with Temperature Sensor The AD7747 is a high-resolution, ∑−Δ capacitance-to-digitalconverter (CDC). The capacitance to be measured is connecteddirectly to the device inputs. The architecture features inherenthigh resolution (24-bit no missing codes, up to 18 biteffectiveresolution), high linearity (±0.01%), and high accuracy (±8 fF factory calibrated).
