TDA7493 3 W + 3 W 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. Thanks to the high efficiency and to the exposed-pad-down (EPD) package no separate heatsink is required.

技术特性
  • 3.0 W + 3.0 W of continuous output power with RL = 4 Ω, THD = 10%, VCC= 5 V (filterless)
