ZMD31020 Overview
ZMD31020 is a CMOS integrated circuit for highlyaccurate amplification and sensor-specific correction of bridge sensor signals. The device provides digital pensation of sensor offset, sensitivity, temperature drift and non-linearity by a 16-bit RISC micro controller running a correction algorithm. ZMD31020 acmodates nearly all piezo-resistive bridge sensor types.
