ZSC31015EEG1-R

ZSC31015EEG1-R is a RBicdLite™ analogue output sensor signal conditioner with diagnostic in a 8 pin SOP package. The ZSC31015 is adjustable to nearly all piezoresistive bridge sensors. Measured and corrected bridge values are provided at the SIG™ pin, which can be configured as an analogue voltage output or as a one-wire serial digital output. The digital one-wire interface (OWI) can be used for a simple PC-controlled calibration procedure to program a set of calibration coefficients into an on-chip EEPROM. The calibrated ZSC31015 and a specific sensor are mated digitally: fast, precise, and without the cost overhead associated with trimming by external devices or laser. Integrated diagnostics functions make the ZSC31015 particularly well suited for automotive applications.

• Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity
• Programmable analogue gain and digital gain; accommodates bridges with spans <lt/> 1mV/V and high offset
• Many diagnostic features on chip
• Independently programmable high and low clipping levels
• 24bit customer ID field for module traceability
• Internal temperature compensation reference (no external components)
• Fast power-up to data out response; output available 5ms after power-up
• Current consumption depends on programmed sample rate
• High voltage protection up to 30V with external JFET
• Wide operation temperature: -50°C to 150°C, supply voltage 2.7 to 5.5V with external JFET 5.5 to 30V
