ZSC31050 Overview
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 pensation of sensor offset, sensitivity, temperature drift, and nonlinearity via a 16-bit RISC microcontroller running a polynomial correction algorithm. The ZSC31050 acmodates virtually any bridge sensor type (e.g., piezo-resistive,...
