2. The HART specification requires carrier detect (CD) to be active between 80 and 120 mVpp. Setting CDREF at AREF 0.08 VDC will set
the carrier detect to a nominal 100 mVpp.

3. The modulator output frequencies are proportional to the input clock frequency (460.8 kHz/920 kHz/1.8 MHz).
Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
