(11) Power-supply sequencing requirements must be observed. See Power Supplies section for more information.
(12) Quiescent current increases when the current limit is increased (see Typical Characteristics).
(13) The OPA564 typically goes into thermal shutdown at a junction temperature above +140°C.
(14) Thermal modeling of the DWD-20 package was done based on a 1-inch AAVID Thermalloy heatsink (Thermalloy part no. 65810).
