WebAD7745 and AD7746 are designed for floating capacitive sensors, meaning neither trace on the capacitive sensor input pins is grounded. Of these, the AD7745 allows for one channel of conversion, while the AD7746 allows for two (identical otherwise). Either channel can be setup as a single-ended or differential input channel. WebThe AD7745/AD7746 have a 2-wire, I 2 C-compatible serial interface. Both parts can operate with a single power supply from 2.7 V to 5.25 V. They are specified over the automotive temperature range of –40°C to +125°C and are housed in a 16-lead TSSOP … WebThe AD7745 / AD7746 are a high resolution, Σ-Δ capacitance-to-digital converter (CDC). The capacitance to be measured is connected directly to the device inputs. The architecture fea-tures inherent high resolution (24-bit no missing codes, up to 21-bit effective resolution), high linearity (±0.01%), and high accuracy (±4 fF factory calibrated). cloak and dagger 2018 cast
