Brief Description
The ZSC31014 is a CMOS integrated circuit for highly accurate amplification and analog-to-digital conversion of differential and half-bridge input signals. The ZSC31014 can compensate the measured signal for offset, 1st and 2nd order span, and 1st and 2nd order temperature (Tco and Tcg). It is well suited for sensor-specific correction of bridge sensors. Digital compensation of signal offset, sensitivity, temperature drift, and non-linearity is accomplished via an internal digital signal processor running a correction algorithm with calibration coefficients stored in a non-volatile EEPROM.

FEATUREs
• High accuracy (±0.1% FSO @ -25 to +85°C;
   ±0.25% FSO @ -40 to +125°C)
• 2nd order charge-balancing analog-to-digital
   converter provides low noise, 14-bit data at
   sample rates exceeding 2kHz
• Fast power-up to data output response:
   3ms at 4MHz
• Digital compensation of sensor offset, sensitivity,
   temperature drift, and non-linearity
• Eight programmable analog gain settings 
   combine with a digital gain term; accommodates
   bridges with spans <1mV/V and high offset
• Internal temperature compensation for sensor
   correction and for corrected temperature output
• 48-bit customer ID field for module traceability

Benefits
• Simple PC-controlled configuration and 
   single-pass digital calibration via I2C™ interface – quick
   and precise; SPI option for measurement mode
• Eliminates need for external trimming
   components
• On-chip diagnostic features add safety to the
   application (e.g., EEPROM signature, bridge
   connection checks, bridge short detection).
• Low-power Sleep Mode lengthens battery life
• Enables multiple sensor networks
