Product Summary
The ZMD31050DIG1 is a CMOS integrated circuit for highly-accurate amplification and sensor-specific correction of bridge sensor signals. The ZMD31050DIG1 provides digital compensation of sensor offset, sensitivity, temperature drift and non-linearity by a 16-bit RISC micro controller running a correction algorithm with correction coefficients stored in non-volatile EEPROM. The ZMD31050DIG1 accommodates virtually any bridge sensor (e.g. piezo-resistive, ceramic-thickfilm or steel membrane based).
