TDA7492 [STMicroelectronics]

TDA7492 Amplifier Description


The TDA7492 is a dual BTL class-D audio amplifier with a single power supply that is intended for use in LCD TVs and monitors. Only a minimal heatsink is required due to the high efficiency and exposed-pad-up (EPU) packaging. Overvoltages, undervoltages, overcurrents, and thermal overloads are all adequately protected by the TDA7492.


TDA7492 Amplifier Features


Short-circuit protection
50 W + 50 W continuous output power at THD = 10% with RL = 6 ? and VCC = 25 V
40 W + 40 W continuous output power at THD = 10% with RL = 8 ? and VCC = 25 V
Wide-range single-supply operation (8 - 26 V)
High efficiency (? = 90%)
Four selectable, fixed gain settings of nominally 21.6 dB, 27.6 dB, 31.1 dB and 33.6 dB
Standby & mute features
Externally synchronizable
ECOPACK?, environmentally friendly package
Thermal overload protection
Differential inputs minimize common-mode noise
