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 sound cards, including the Sound Blaster Pro 2.0, Sound Blaster 16 ASP and AWE family.

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