Brief Description
The ZSC31014 RBiciLite™ is a CMOS integrated circuit for highly accurate amplification and analog-todigital conversion of differential and half-bridge input signals. The RBiciLite™ can compensate the measured signal for offset, 1st and 2nd order span, and 1st and 2nd order temperature (Tco and Tcg). It is wellsuited 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 or optional external temperature
compensation for sensor correction and for corrected
temperature output
• 48-bit customer ID field for module traceability
Benefits
• Simple PC-controlled configuration and
ingle-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
