High-End 18-Bit Sensor Signal Conditioner

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. The measured and corrected sensor values are provided at the digital output pins, which can be configured as I2C (≤ 3.4MHz) or SPI (≤ 20MHz). Digital compensation of signal offset, sensitivity, temperature, and non-linearity is accomplished via a 26-bit internal digital signal processor (DSP) running a correction algorithm. Calibration coefficients are stored on-chip in a highly reliable, nonvolatile, multiple-time programmable (MTP) memory. Programming the ZSSC3218 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 ZSSC3218 provides accelerated signal processing, increased resolution, and improved noise immunity in order to support high-speed control, safety, and real-time sensing applications with the highest requirements for energy efficiency.


  • 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% full-scale output at -40°C to 85°C
