描述
The ZSSC3230 is a CMOS integrated circuit for accurate capacitance-to-digital conversion and sensor-specific correction of capacitive sensor signals. Digital compensation of sensor offset, sensitivity, and temperature drift is accomplished via an internal digital signal processor running a correction algorithm with calibration coefficients stored in a non-volatile, multiple-time programmable (MTP) memory. Programming the ZSSC3230 is simple via the serial interface. The interface is used for the PC-controlled calibration procedure, which programs the set of calibration coefficients in memory. The ZSSC3230 is configurable for capacitive sensors with capacitances up to 30pF and will provide a scalable up to 18-bit output resolution. It is compatible with single-ended capacitive sensors. Measured and corrected sensor values can be output as I²C (≤ 3.4MHz).
The ZSSC3230 provides accelerated signal processing, increased resolution, and improved noise immunity to support high-speed control, safety, and real-time sensing applications with the highest requirements for energy efficiency.
