Brief Description
The ZSSC3154 is an integrated circuit for highly accurate amplification and sensor-specific correction of a bridge sensor signal. Up to two temperature sensors can also be read in parallel.
The circuitry provides different configurations of the analog outputs to show two measurement results simultaneously. This also allows generating a complementary bridge sensor signal, which is often a requirement in safety-relevant applications.
FEATUREs
• Differential bridge sensor input
• Half-bridge sensor or temperature sensor input
• Digital compensation of offset, gain, nonlinearity,
and temperature dependency
• Two analog outputs; behavior programmable by
EEPROM configuration
• Sequential analog output mode provides two
measurement values at one output pin
• On-chip diagnostic and safety features including
sensor connection diagnostic and broken-chip
detection
• 2 EEPROM words for arbitrary user data
• Multiple configurable output options
Benefits
• Bridge sensor signal validation for safety
applications via two antivalent analog outputs or
via half-bridge sensor measurement output
• Simultaneous measurement of sensor signals,
including temperature signal for compensation
and for temperature output
• Efficient use of non-calibrated elements for
bridge sensors and temperature sensors without
external trimming components
• Single-pass end-of-line calibration algorithm
minimizes production costs
• Excellent EMC/ESD robustness and AEC-Q100
qualification
