製品概要
概要
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. Thanks to the high efficiency and to the exposed-pad-down (EPD) package no separate heatsink is required.
