AD5755 power supply

some questions about AD5755 power supply:

1. I want to use only 0 - 10V, 0 - 20mA and 4 - 20mA ouput signals. Is a dual voltage supply +/- 15V still required ?

    Or can I use +24V for AVDD and 0V for AVSS ?

2. CN-0198 shows a 5V supply circuit for AD5755. Max.VIN of the ADP2300 is only 20V. Which other regulator would be suitable

    for VIN = 24V ?

3. Does something speak against operating DVDD and AVCC from the same 5V supply ?
