The ZSSC4151 is a CMOS integrated circuit for highly accurate amplification and sensor-specific correction of resistive bridge sensor signals. Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity is accomplished via an internal 16-bit RISC microcontroller running a correction algorithm, with calibration coefficients stored in an integrated EEPROM. The ZSSC4151 is adjustable to nearly all resistive bridge sensor types. Measured values are provided at the analog voltage output and at the optional digital I2C or the ZACwire™ interface, also referred to as the one-wire interface (OWI). The digital interfaces can be used for a simple PC-controlled calibration procedure to program a set of calibration coefficients into an on-chip EEPROM. The ZSSC4151 and the calibration equipment communicate digitally, so the noise sensitivity is greatly reduced. Digital calibration helps keep assembly cost low as no trimming by external devices or lasers is needed.

Features

  • Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity
  • Adjustable to nearly all full or half bridge sensors
  • Analog gain of 200, supporting sensors with spans down to 1mV/V using the digital zooming option
  • Output options: ratiometric 12-bit analog voltage output (e.g., 5-95% or 10-90%) with freely adjustable clamping or ZACwire™ digital one-wire-interface (OWI)
  • Temperature compensation: internal or external diode, bridge external series resistance, or RTD
  • Sensor biasing by internal voltage
  • High voltage and reverse polarity protection up to 40V at all module pins: VDDE, VSSE, and AOUT
  • Maximum supply current: 7mA
  • Short-circuit protection for AOUT
  • Traceability via user-defined registers
