ZSC31015EAG1-T

ZSC31015 is a resistive sensor signal conditioner with analogue output and diagnostic features. It is a CMOS integrated circuit for highly accurate amplification and sensor-specific correction of bridge sensor signals. Digital compensation of sensor 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. The ZSC31015 is adjustable to nearly all piezo-resistive bridge sensors. Measured and corrected bridge values are provided at the SIG™ pin, which can be configured as an analogy voltage output or as a one-wire serial digital output. The digital one-wire interface can be used for a simple PC-controlled calibration procedure to program a set of calibration coefficients into an onchip EEPROM.

• Digital compensation of sensor offset, sensitivity, temperature drift and nonlinearity
• Independently programmable high and low clipping levels
• 24bit customer ID field for module traceability
• Digital calibration and configuration via one-wire interface quick and precise
• Internal temperature compensation reference (no external components)
• Option for external temperature compensation with addition of single diode
• Fast power-up to data output response, output available 5ms after power up
• Current consumption depends on programmed sample rate 1mA down to 250
• High voltage protection up to 30V with external JFET, fast response time is 1ms (typical)
• 8 pin SOIC package, temperature range from -40 to 125°C
