ZSSC3230 Description
The ZSSC3230 is a CMOS integrated circuit for accurate capacitance-to-digital conversion and sensor-specific correction of capacitive sensor signals. Digital pensation of sensor offset, sensitivity, and temperature drift is acplished via an internal digital signal processor running a correction algorithm with calibration coefficients stored in a nonvolatile, multiple-time programmable (NVM) memory. Programming the...
