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 EN.

The parts have a standard voltage input, which together with the differential reference input allows easy interface to .

The AD7745/AD7746 are a high resolution, Σ-Δ capacitance-todigital converter (CDC). The capacitance to be measured is connected directly to the device inputs. The architecture features inherent high resolution (24-bit no missing codes, up to 21-bit e.
