3 W + 3 W dual BTL class-D audio amplifier
November 2010 Doc ID 14570 Rev 6 1/30
TDA74933-watt + 3-watt dual BTL class-D audio amplifier
Features 3.0 W + 3.0 W of continuous output power with =4 Ω, THD = 10%, VCC = 5 V (filterless) 2.8 W + 2.8 W of continuous output power with =4 Ω, THD = 10%, VCC = 5 V (with filter) Single supply voltage range 3.0 V to 5.5V High efficiency (η = 83%) Four selectable, fixed gain settings of dB, 12 dB, 15.6 dB and 18 dB Differential inputs minimize common-mode
noise Filterless operation Standby feature Short-circuit protection Thermal-overload protection Externally synchronizable
DescriptionThe 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.
