FDC1004DGST

The FDC1004DGST from Texas Instruments is a high-resolution, 4-channel capacitance-to-digital converter ideal for implementing capacitive sensing solutions. This device supports a full-scale range of ±15pF per channel and can handle an offset capacitance of up to 100pF, allowing for the use of remote sensors. It includes integrated shield drivers to help reduce EMI interference and focus sensing direction.

Key electrical specifications include a supply voltage range of 3V to 3.6V, an active current consumption of 750µA, and a standby current of 29µA. The interface type is I2C, and the resolution is 16 bits. The operating temperature range is -40°C to 125°C.

The FDC1004DGST is available in a 10-VSSOP package and is suitable for surface mounting. Its capabilities make it applicable for various applications such as proximity sensing, gesture recognition, material analysis, and remote liquid level sensing. The device's design facilitates low-power, low-cost, and high-resolution contactless sensing.

This converter is designed for applications requiring precise capacitance measurements. The inclusion of shield drivers and the ability to manage significant offset capacitance contribute to its versatility and performance in challenging environments. Its small footprint and surface-mount capability make it suitable for space-constrained designs.
