Description
This application note discusses the PIC14C000 calibration constants and calibration procedures. This application note refers to the following documents: ? PIC14C000 Data Sheet (DS40122) ? AN575, ?IEEE 754 Compliant Floating Point Routines? (DS00575) ? AN624 ?PIC14C000 A/D Theory and Implementation? (DS00624) The PIC14C000 has several analog peripherals. Like all CMOS circuitry the parametric values vary with process, temperature, voltage, and time. The PIC14C000 has been designed to minimize the effect of these variations. In addition, each device is calibrated at factory test by measuring several key parameters and storing these values into EPROM at specified locations. The customer?s application program may access this data and use it to mathematically compensate for device variations. Collectively, these data values are referred to as calibration constants. They are listed in Table 4-1 in the PIC14C000 Data Sheet (DS40122).
