TDA7493 Datasheet (STMicroelectronics) - 3-watt + 3-watt dual BTL class-D audio amplifier

TDA7493, 3-watt + 3-watt dual BTL class-D audio amplifier

The TDA7493 is a dual BTL class-D audio amplifier, specially designed for LCD TV, LCD monitors or small speakers on cradles with single-supply operation.

The filterless operation allows the external component count to be reduced.

The TDA7493 is assembled in the HTSSOP24 package.
