Brief Description
The ZSSC3224 is a sensor signal conditioner (SSC) IC 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 ZSSC3224 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 24-bit analog-to-digital converter (ADC)
• Fully programmable gain amplifier for optimizing
   sensor signals: gain range 6.6 to 216 (linear)
• Internal auto-compensated 18-bit 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., 18-bit conditioned sensor
   signal measurement rate >200s-1
• Typical sensor elements can achieve an accuracy of
   better than ±0.10% FSO* at -40 to 85°C
