What are the limits for the MAX1452's analog output voltage?
According to the MAX1452 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.
