Hello TI!
Our company have receaved OPA277UA but on entrance control we have problem with quality service to indentify the component.
Does later 'A' in left up corner mean that is opa277uA? Datasheet in 'PACKAGE OPTION ADDENDUM' page 29 in annotation (4) sad that "There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device"
