HTSSOP24 package with exposed pad down
Description
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.
