The AD7745ARUZ is a high-resolution, 24-bit capacitance-to-digital converter (CDC) from Analog Devices. It is designed to interface directly with single or differential floating capacitive sensors, converting capacitance changes into a digital output with up to 21 effective number of bits (ENOB). The device offers a full-scale capacitance range of ±4 pF and can tolerate common-mode capacitance up to 17 pF and parasitic capacitance to ground up to 60 pF.
Key electrical specifications include a capacitance accuracy of ±4 fF, linearity of ±0.01%, and a resolution down to 4 aF. The update rate is programmable from 10 Hz to 90 Hz. The device operates from a single 2.7 V to 5.25 V supply and draws a typical supply current of 0.7 mA. An on-chip temperature sensor provides 0.1°C resolution with ±2°C accuracy.
The AD7745ARUZ communicates via an I2C-compatible 2-wire serial interface. It is housed in a 16-lead TSSOP package and is specified for surface mount mounting. The operating temperature range is -40°C to +125°C, making it suitable for industrial and automotive environments.
