The ADM205, ADM206, ADM211 and ADM213 feature a low power shutdown mode which reduces power dissipation to less than 5 µW making them ideally suited for battery powered equipment. The ADM205 does not require any external components and is particularly useful in applications where printed circuit board sp...
