Renesas Electronics ZSC31050
ZSC31050 is a CMOS integrated circuit for highly accurate amplification and sensor-specific correction of bridge sensor and temperature sensor signals. The device provides digital compensation of sensor offset, sensitivity, temperature drift, and nonlinearity via a 16-bit RISC microcontroller running a polynomial correction algorithm. The ZSC31050 accommodates virtually any bridge sensor type (e.g., piezo-resistive, ceramic thick-film, or steel membrane based).DESCRIPTION
In addition, it can interface to a separate temperature sensor. The bi-directional digital interfaces (I2C, SPI, and ZACwire™) can be used for a simple PC-controlled one-pass calibration procedure to program a set of calibration coefficients into an on-chip EEPROM. A specific sensor and a ZSC31050 can be mated digitally: fast, precise, and without the cost overhead associated with trimming by external devices or laser. The ZACwire™ interface enables an endof-line calibration of the sensor module. Typical applications for the ZSC31050 include industrial, medical, and consumer products. It is specifically engineered for most resistive bridge sensors; e.g., sensors for measuring pressure, force, torque, acceleration, angle, position, and revolution.FEATURES
