AD7150 Capacitance Converter for Proximity Sensing Addresses Power and Sensitivity Requirements
The document introduces the Analog Devices AD7150, an ultralow power capacitance-to-digital converter designed specifically for proximity sensing applications. Key features include two independent input channels, operation over a wide temperature range of -40°C to +85°C, and an on-chip adaptive environmental calibration feature that automatically recalibrates against changes in humidity, dust, or temperature.
It is designed as a complete signal processing solution specifically for proximity sensors.
The AD7150 is specified to operate over a temperature range of -40°C to +85°C.
