The data sheet for the ADRF5731 shows a supply current of 117,-117 microamperes. Is this correct ??? as it seems to be "low". Any input is appreciated.
Yes - this is correct. Under nominal operating conditions, the ADRF5731 typically draws 117uA on Vdd and -117uA on VSS.
Please note, the part draws higher current (still <1mA) when operating the controls closer to the threshold levels, instead of rail voltages.
Operating over different temperatures also affects the current draw.
