The AD7747ARUZ is a high-resolution, Sigma-Delta capacitance-to-digital converter (CDC) designed by Analog Devices. It provides a 24-bit resolution, with an effective resolution up to 19.5 bits, and boasts high linearity of ±0.01% and accuracy of ±10 fF. The device supports a full-scale capacitance range of ±8 pF and can handle common-mode capacitance up to 17 pF.
Featuring an on-chip temperature sensor with 0.1°C resolution and ±2°C accuracy, the AD7747ARUZ is suitable for applications requiring integrated environmental monitoring. It operates from a single supply voltage of 2.7 V to 5.25 V with a low current consumption of 0.7 mA. The converter includes an internal clock oscillator and a 2-wire I2C-compatible serial interface, minimizing external component requirements.
Packaged in a 16-lead TSSOP, the AD7747ARUZ is designed for surface mount applications. Its operating temperature range is -40°C to +125°C, making it suitable for demanding industrial, automotive, and medical systems. Applications include pressure measurement, position sensing, proximity sensing, level sensing, and flow metering.
