Overview
The FDC1004DGST is a four-channel capacitance-to-digital converter manufactured by Texas Instruments, designed for capacitive sensing solutions. It operates within a supply voltage range of 3 V to 3.6 V and features a 16-bit resolution for precise measurements. The device supports I2C communication interfaces and functions as a proximity sensor with active shielding capabilities to mitigate interference. It is housed in a 10-pin VSSOP package and is rated for an operating temperature range from -40°C to +125°C.
Feature Summary
- Integrates active shielding technology to reduce system interference and concentrate the sensing area for improved reliability.
- Provides high-resolution digital conversion of capacitance changes across four independent channels.
- Supports standard I2C communication protocols for straightforward integration into host systems.
Applications
- Capacitive touch sensing interfaces
- Proximity detection systems
- Liquid level sensing applications
Procurement Notes
Verify the specific suffix DGST corresponds to the 10-VSSOP package variant when sourcing. Confirm the extended industrial temperature rating aligns with environmental requirements. Ensure compatibility with the 3V to 3.6V power supply specifications during component selection.
Selection Notes
Select this component for designs requiring multi-channel capacitance measurement with integrated noise reduction. Consider the VSSOP package constraints for PCB layout. Validate that the I2C interface matches the host controller's capabilities and address configuration needs.
Part Context
This part belongs to the FDC1004 family of capacitance-to-digital converters. Variants such as FDC1004DSCR and FDC1004DSCT share similar functional cores but differ in packaging options like WSON. The DGST suffix specifically denotes the VSSOP form factor suitable for space-constrained applications.
Replacement Considerations
FDC1004Q serves as the automotive-grade equivalent within the same family. Other variants like FDC1004DSCR offer alternative packaging while maintaining core functionality. Verify pinout and package dimensions before substituting.
