i have 20 opamps like opa699 under use, which operate at dual supply +5V and also -5V each opamp would require a quiescent current of 20mA , i am not clear whether both the power supplies +5 and -5 require 20mA to be supplied , but on a whole for such 20opamps i would require 400mA of current
so i feel i now require a dcdc or regulator which takes my input of 28V and gives out +5V and -5V dual supply with a current of 400mA max
kindly suggest a dcdc for my above requirements
