Описание

The AD7745ARUZ is a 1-channel 24-bit High Resolution Capacitance to Digital Converter with temperature sensor. 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 effective resolution). Each channel can be configured as single-ended or differential. The Σ-∆ capacitance to digital converter (CDC) is designed for floating capacitive sensors. The parts have an on-chip temperature sensor with a resolution of 0.1°C and accuracy of ±2°C. The on-chip voltage reference and the on-chip clock generator eliminate the need for any external components in capacitive sensor applications. The parts have a standard voltage input, which together with the differential reference input allows easy interface to an external temperature sensor, such as an RTD, thermistor or diode. The AD7745 has a 2-wire I²C-compatible serial interface.
