Description
AI
Capacitive sensing with grounded capacitor sensors is a very low-power, low-cost, high-resolution contact-less sensing technique that can be applied to a variety of applications ranging from proximity sensing and gesture recognition to material analysis and remote liquid level sensing. The sensor in a capacitive sensing system is any metal or conductor, allowing for low cost and highly flexible system design.
The FDC1004-Q1 is a high-resolution, AEC-Q100 qualified, 4-channel capacitance-to-digital converter for implementing capacitive sensing solutions. Each channel has a full scale range of ±15pF and can handle a sensor offset capacitance of up to 100pF, which can be either programmed internally or can be an external capacitor for tracking environmental changes over time and temperature. The large offset capacitance capability allows for the use of remote sensors.
The FDC1004-Q1 also includes shield drivers for sensor shields, which can reduce EMI interference and help focus the sensing direction of a capacitive sensor. The small footprint of the FDC1004-Q1 allows for use in space-constrained applications. The FDC1004-Q1 is available in a 10-pin VSSOP package, which allows for optical inspection in production, and features an I2C interface for interfacing to an MCU.
