Brief Description
The ZSSC3026 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 ZSSC3026 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
• Digital compensation of 1st and 2nd order temperature gain and offset drift
• Intelligent power management unit
• Layout customized for die-die bonding with
   sensor for high-density chip-on-board assembly
• Typical sensor elements can achieve accuracy
   of less than ±0.10% FSO @ -40 to 110°C

Typical Applications
The ZSSC3026 is designed for operation in
calibrated resistive (pressure) sensor modules:
• Barometric altitude measurement for portable
   navigation
• Altitude measurement for emergency call
   systems
• Altitude measurement for car navigation
• Inside hard disk pressure measurement
• Weather forecast
