The AD7746ARUZ-REEL7 is a high-resolution, Sigma-Delta capacitance-to-digital converter (CDC) from Analog Devices. It offers a 24-bit resolution and up to 21-bit effective resolution, with high linearity of 0.01% and accuracy of 4 fF.
This device interfaces directly to single or differential floating sensors and has a full-scale capacitance range of ±4 pF, while tolerating parasitic capacitance to ground up to 60 pF. It includes an on-chip temperature sensor with 0.1°C resolution and ±2°C accuracy.
The AD7746ARUZ-REEL7 operates from a single 2.7V to 5.25V supply with a low current consumption of 0.7 mA. It is housed in a 16-lead TSSOP package and is suitable for surface mounting. The operating temperature range is -40°C to +125°C.
Applications include automotive, industrial, and medical systems for pressure measurement, position sensing, level sensing, flowmeters, humidity sensing, and impurity detection.
The supply voltage range is 2.7V to 5.25V, operating from a single supply.
It operates from -40°C to +125°C.
It is available in a 16-TSSOP surface-mount package (0.173", 4.40mm width).
Yes, it is listed as RoHS3 compliant, though this is unverified.
The resolution is 24 bits.
It has two input channels.
The device offers 4 fF accuracy and 0.01% linearity.
