Brief Description
The ZSSC3218 is a sensor signal conditioner (SSC) integrated circuit for high-accuracy amplification and analog-to-digital conversion of a differential or pseudo-differential input signal. Designed for high-resolution sensor module applications, the ZSSC3218 can perform offset, span, and 1st and 2nd order temperature compensation of the measured signal. Developed for correction of resistive bridge or absolute voltage sensors, it can also provide a corrected temperature output measured with an internal sensor.

FEATUREs
• Flexible, programmable analog front-end design;
   up to 18-bit analog-to-digital converter (ADC)
• Fully programmable gain amplifier for optimizing
   sensor signals: gain range 6.6 to 216 (linear)
• Internal auto-compensated temperature sensor
• Digital compensation of individual sensor offset;
   1st and 2nd order digital compensation of sensor
   gain as well as 1st and 2nd order temperature gain
   and offset drift
• Programmable interrupt operation
• High-speed sensing: e.g. 16-bit conditioned
   sensor signal measurement rate >500s-1
• Typical sensor elements can achieve an 
   accuracy of better than ±0.10% FSO** at -40 to 85°C
