Check ST's datasheet: https://www.st.com/content/st_com/en/products/amplifiers-and-comparators/operational-amplifiers-op-amps/standard-op-amps/ts272.html

"D" would be the SO package, "R" is undeclared. Perhaps not a ST part.

The second line is usually a factory/date code. Nothing in the specific ST datasheet.
