The bi-directional digital interfaces (I2C, SPI, ZACwireTM) can be used for a simple PC-controlled one-shot calibration procedure, in order to program a set of calibration coefficients into an on-chip EEPROM. Thus a specific sensor and a ZMD31050 are mated digitally: fast, precise and without the cost overhead associated with laser trimming, or mechanical potentiometer methods. Application kit available (SSOP16 samples, calibration PCB, calibration software, technical documentation)
