AD7747 Datasheet and Product Info | Analog Devices
WEBJan 1, 2007 · The AD7747 is designed for single-ended or differential capacitive sensors with one plate connected to ground. For floating (not grounded) capacitive sensors, the AD7745 or AD7746 are recommended. The part has an on-chip temperature sensor with a resolution of 0.1°C and accuracy of ±2°C.
WEBThe AD7747 is a high-resolution, Σ-Δ capacitance-to-digital 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 19.5-bit effective resolution), high linearity (±0.01%), and high accuracy (±10 fF factory calibrated).
WEBIn addition to the converter, the AD7745/AD7746 integrates a multiplexer, an excitation source and CAPDACs for the capa-citive inputs, a temperature sensor, a voltage reference for the voltage and temperature inputs, a complete clock generator, a control and calibration logic, and an I2C-compatible serial interface.
WEBThe AD7747 is designed for grounded capacitive sensors, where one trace on the capacitive sensor input pins is grounded, and supports one channel. In most cases, designers should look to utilize the AD7745/6 instead of the AD7747, as the AD7747 is much more prone to parasitics.
