Frequently Asked Questions

How many channels does FDC2214 have?

FDC2214 provides 4 independent capacitive sensing channels, each with 28-bit resolution. Channels can be multiplexed or run continuously. For 2-channel applications, the FDC2114 variant is also available at lower cost.

What resolution does FDC2214 achieve?

FDC2214 achieves 28-bit resolution, translating to sub-femtofarad sensitivity. This extreme resolution enables detection through thick overlays (up to 15mm plastic or glass), making it ideal for automotive buttons that must work through protective panels.

How does FDC2214 handle environmental changes?

FDC2214 uses LC resonant sensing that is inherently immune to slow environmental changes like temperature, humidity, rain, and contamination. The high-frequency measurement (up to 10MHz) rejects low-frequency noise sources that affect traditional capacitive sensing.

What interface does FDC2214 use?

FDC2214 communicates via standard I2C bus (up to 400kHz). The I2C address is pin-configurable for multi-device systems. Register-based configuration allows setting measurement speed, reference, and channel selection. An interrupt pin signals data-ready or fault conditions.
