REGISTER 13—OFFSET REMOVAL AND SIGNAL GAIN REGISTER
Register 13—Offset Removal and Signal Gain Register Comments
Because the linear demodulator output is proportional to frequency, it usually consists of an offset combined with a relatively
low signal. The offset can be removed, up to a maximum of 1.0, and gained to use the full dynamic range of the DAC, as follows:
DAC_Input = (2^ Test_DAC_Gain) × (Signal − Test_DAC_Offset_Removal/4096).
