ZSC31150KIT

Data Sheet Rev. 1.07 / August 2010 ZSC31150 Fast Automotive Sensor Signal Conditioner ZSC31150 Fast Automotive Sensor Signal Conditioner Brief Description Benefits The ZSC31150 is a CMOS integrated circuit for No external trimming components required highly-accurate amplification and sensor-specific Only a few external protection devices needed correction of bridge sensor signals. Digital PC-controlled configuration and One-Shot TM TM compensation of sensor offset, sensitivity, calibration via IC or ZACwire interface: temperature drift, and non-linearity is Simple, cost efficient, quick, and precise accomplished via an internal 16-bit RISC TM TM End-of-Line calibration via IC or ZACwire microcontroller running a correction algorithm, with interface calibration coefficients stored in an EEPROM. High accuracy (0.25% FSO -25 to 85C The ZSC31150 is adjustable to nearly all bridge 0.5% FSO -40 to 125C) sensor types. Measured values are provided at the The ZSC31150 is optimized for automotive TM analog voltage output or at the digital ZACwire environments by its special protection circuitry TM and IC interface. The digital interface can be and excellent electromagnetic compatibility used for a simple PC-controlled calibration procedure, in order to program a set of calibration coefficients into an on-chip EEPROM. Thus, a Available Support specific sensor and a ZSC31150 are mated Evaluation Kits digitally: fast, precise, and without the cost Application Notes overhead associated with trimming by external Mass calibration setup devices or a laser.
