TDA7492
50 W + 50 W dual BTL class-D audio amplifier
Features
■ 50 W + 50 W continuous output power at
THD = 10% with R_L = 6 Ω and V_CC = 25 V
■ 40 W + 40 W continuous output power at
THD = 10% with R_L = 8 Ω and V_CC = 25 V
■ Wide-range single-supply operation (8 - 26 V)
■ High efficiency (η = 90%)
■ Four selectable, fixed gain settings of
nominally 21.6 dB, 27.6 dB, 31.1 dB and
33.6 dB
■ Differential inputs minimize common-mode
noise
■ Standby and mute features
■ Short-circuit protection
■ Thermal overload protection
■ Externally synchronizable
■ ECOPACK^®, environmentally-friendly package

with exposed pad up
Description
The TDA7492 is a dual BTL class-D audio
amplifier with single power supply designed for
LCD TVs and monitors.
Thanks to the high efficiency and exposed-pad-up
(EPU) package only a simple heatsink is required.
