RBic Digital Output Sensor ilite ZSC31014 Datasheet Signal Conditioner Brief Description Benefits The ZSC31014 is a CMOS integrated circuit for Simple PC-controlled configuration and single- 2 highly accurate amplification and analog-to-digital pass digital calibration via I C interface quick conversion of differential and half-bridge input and precise SPI option for measurement mode signals. The ZSC31014 can compensate the mea- Eliminates need for external trimming st nd st sured signal for offset, 1 and 2 order span, and 1 components nd and 2 order temperature (Tco and Tcg). It is well On-chip diagnostic features add safety to the suited for sensor-specific correction of bridge sen- application (e.g., EEPROM signature, bridge sors. Digital compensation of signal offset, connection checks, bridge short detection). sensitivity, temperature drift, and non-linearity is Low-power Sleep Mode lengthens battery life accomplished via an internal digital signal processor Enables multiple sensor networks running a correction algorithm with calibration coefficients stored in a non-volatile EEPROM. The ZSC31014 is adjustable to nearly all piezo- Available Support resistive bridge sensors. Measured and corrected Evaluation Kit bridge values are provided at digital output pins, Application Notes 2 which can be configured as I C* or SPI. The digital 2 Mass Calibration Solution I C interface can be used for a simple PC- controlled calibration procedure to program cali- bration coefficients into an on-chip EEPROM. The Physical Characteristics calibrated ZSC31014 and a specific sensor are Wide supply voltage capability: 2.7V to 5.5V mated digitally: fast, precise, and without the cost Current consumption as low as 70A depending overhead associated with trimming by external on programmed sample rate devices or laser trimming. Low-power Sleep Mode (<2A 25C) The ZSC31014s integrated diagnostics functions Operation temperature: -40C to +125C are well suited for safety-critical applications.
