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.
3.0 W + 3.0 W of continuous output power with RL = 4 Ω, THD = 10%, VCC= 5 V (filterless)
2.8 W + 2.8 W of continuous output power with RL = 4 Ω, THD = 10%, VCC= 5 V (with filter)
Single supply voltage range 3.0 V to 5.5 V
High efficiency (η = 83%)
Four selectable, fixed gain settings of6 dB, 12 dB, 15.6 dB and 18 dB
