TDA7493
3 W + 3 W dual BTL class-D audio amplifier
Features
3.0 W + 3.0 W continuous output power
RL =4 , THD = 10%, VCC = 5 V (filterless)
2.8 W + 2.8 W continuous output power
RL =4 , 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 of
6 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
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.
