FDC1004DGSR TI Capacitance-to-Digital Converters

The FDC1004DGSR is a 4-channel, capacitance-to-digital converter from Texas Instruments designed for proximity sensing and liquid level sensing applications. The device features 4 capacitive sensor inputs, a 16-bit resolution, and EMI-resistant architecture for robust operation in noisy environments. It operates over a supply range of 3V to 3.6V and offers programmable excitation frequency. The device features I2C interface for configuration and data readout, low power consumption, and includes shield drivers for active shielding of sensor lines. Housed in a 10-pin VSSOP (DGS) package, it operates over -40°C to 125°C. Applications include proximity detection, gesture recognition, liquid level sensing, touch buttons, and industrial automation.
