The Yamaha YMF262, also known as the OPL3 (OPL is an acronym for FM Operator Type-L), is an FM synthesis sound chip by Yamaha. It is an improved version of the Yamaha YM3812 (OPL2).

The YMF262 was used in many ISA[note 1] sound cards, including the Sound Blaster Pro 2.0, Sound Blaster 16 ASP and AWE family.[1]

The OPL3 generates four channel audio as two 16-bit serial data streams. These data streams are designed as input for the YAC512 DAC.[2]
