Brief Description
The ZSSC3036 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 ZSSC3036 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 accepting
   sensors from 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 as well as of 1st and 2nd order temperature
   gain and offset drift
• Fast sensing: 16-bit conditioned sensor signal
   measurement rate at more than 200s-1
• Typical sensor elements can achieve accuracy of
   less than ±0.10% FSO** @ -40 to 110°C

Benefits
• Integrated 18-bit calibration math DSP
• Fully corrected signal at digital output
• Layout customized for die-die bonding with
   sensor for high-density chip-on-board assembly
