Twenty-five suspects were released because of a lack of evidence.
It is the latest batch of death sentences passed in connection with the killings - 36 men were hanged a year ago for their part in the massacre.
ISIS filmed the killings, at the former US base of Camp Speicher, near Tikrit, in an early piece of shock propaganda.
Most of the victims are believed to have been young Shia Muslims who were based at the camp when Tikrit was overrun by ISIS.
Photos and videos published by ISIS at the time showed soldiers being lined up and shot at various locations.
Some bodies were pushed into the River Tigris, while others were buried in mass graves that were found after government forces recaptured the city a year later.
