TDA7492 - 50W + 50W dual BTL class-D audio amplifier

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.

Features

• 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.
• Differential inputs minimize common-mode noise.
• Standby and mute features.
• Short-circuit protection.
• Thermal overload protection.
