ZSSC3122KIT

The ZSSC3122KIT is an evaluation kit containing software and hardware needed for communication and calibration of a cLite family ZSSC3122 low voltage capacitive sensor signal conditioner. The ZSSC3122 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 EEPROM. A PC can communicate with a ZSSC3122 socketed on the SSC evaluation board via the SSC communication board (SSC CB) through a USB connection. The software should function on any Windows 2000/XP/Vista/Windows 7 system after installation of a USB driver. The SSC evaluation board can connect to a capacitive sensor or provide on board capacitors for simulating input from a capacitive sensor.

• Maximum target input capacitance of 10pF
• Sampling rates as fast as 0.7ms at 8bit, 1.6ms at 10bit, 5.0ms at 12bit, 18.5ms at 14bit
• Digital compensation of sensor
• Internal temperature compensation reference
• Programmable capacitance span and offset
• Layout customized for die to die bonding with sensor for low cost, high density chip on board
• High accuracy
• Minimized calibration costs: no laser trimming, one pass calibration using a digital interface
• Excellent for low power battery applications
• Digital compensation of 1st and 2nd order temperature gain and offset drift
