Features
* Capacitance-to-digital converter New standard in single chip solutions Interfaces to single or differential floating sensors Resolution down to 4 aF (that is, up to 21 ENOB) Accuracy: 4 fF Linearity: 0.01% Common-mode (not changing) capacitance up to 17 pF Full-scale (changing) capacitance range: ±4Applications
* The parts have a standard voltage input, which together with the differential reference input allows easy interface to an external temperature sensor, such as an RTD, thermistor, or diode. The AD7745/AD7746 have a 2-wire, I2C-compatible serial interface. Both parts can operate with a single power sAD7746 Distributors
