Additional preview pages of the TDA7491HV datasheet.

The TDA7491HV 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) and down (EPD) packages, no separate heatsink is required.

The TDA7491HV is pin-to-pin compatible with the TDA7491P and TDA7491LP.

20 W + 20 W continuous output power:.
RL = 8 Ω, THD = 10% at VCC = 18 V.
Wide-range single-supply operation (5 - 18 V).
High efficiency (η = 90%).
Four selectable, fixed gain settings of nominally 20 dB, 26 dB, 30 dB and 32 dB.
Differential input minimize common-mode noise.
No ‘pop’ at turn-on/off.
Standby and mute features.
Short-circuit protection.
Thermal overload protection.
External synchroni.
