Question: What is the difference between DAC8562 and DAC8563?
Answer: The reset output level of DAC8562 is 0, and the reset output level of DAC8563 is 1/2 of the output range (Mid scale).
Question: How is the single/bipolar output set?
Answer: DAC8562/3 has a unipolar output. Setting the single/bipolar output can be done by changing the reference level of the output differential amplifier, and selecting between 0 and 1/2 of the output range.
Question: How to set it to unipolar output and require 16 bit resolution?
Answer: Change the reference level of the differential amplifier to 0 and adjust the amplification factor of the differential amplifier to 2 times. (Please refer to the schematic diagram of the application module)
