Brief Description
The ZSSC3016 is a sensor signal conditioner (SSC) integrated circuit for high-accuracy amplification and analog-to-digital conversion of a differential input signal. Designed for high-resolution altimeter module applications, the ZSSC3016 can perform offset, span, and 1st and 2nd order temperature compensation of the measured signal. Developed for correction of resistive bridge sensors, it can also provide a corrected temperature output measured with an internal sensor.

FEATUREs
• Flexible, programmable analog front-end design;
   up to 16-bit scalable, charge-balancing, two-segment
   analog-to-digital converter (ADC)
• Fully programmable gain amplifier for optimizing
   sensor signals: gain range 14 to 72 (linear factor)
• Internal auto-compensated temperature sensor
• Digital compensation of individual sensor offset;
   1st and 2nd order digital compensation of sensor
   gain
• Digital compensation of 1st and 2nd order
   temperature gain and offset drift
• Intelligent power management unit
• Typical sensor elements can achieve accuracy of
   better than ±0.10% FSO @ -40 to 85 °C

Benefits
• Integrated 18-bit calibration math DSP
• Fully corrected signal at digital output
• Minimize calibration costs through the one-pass
   calibration concept
• No external trimming components required
• Highly integrated CMOS design
• Layout customized for die-die bonding with
   sensor for high-density chip-on-board assembly
• Excellent for low-voltage and low-power battery
   applications
