What are the limits for the analog output voltage?
A. According to the data sheet, the analog output voltage can swing between 0.2V and 4.75V. In typical applications, the output is calibrated for 0.5V to 4.5V. As the calibrated output limits approach the data sheet limits, the compensation process can become more difficult as more iteration will be required, mainly because the output runs into the saturation region. • Q. My sensor may be at a different temperature than the signal conditioner. Can I still compensate the sensor? A. Yes. The FSOTC DAC and offset TC DAC provide first-order temperature compensation. This is possible because the reference voltage to FSOTC DAC and offset TC DAC is the BDR (sensor-excitation) voltage, which is temperature dependent. In this case, the internal lookup tables must be filled with a constant value. The compensation process is the same as for the MAX1458/MAX1478. Consult the factory for more details. • Q. Do I have to use the offset TC DAC and FSOTC DAC in my compensation algorithm? A. Not necessar
