I want to use AD5700-1 which has internal oscillator, thus the configuration I am applying to it is as
then will the HART modem work?
and what should make CLKOUT pin? ground or open or Vdd.
Yes, per Table 7 in the datasheet, have XTAL_EN & CLK_CFGx pins as 0b110 respectively, will enable the internal osciallator with no output at CLKOUT. CLKOUT can be left open circuit.
