Additional preview pages of the TDA7491LP datasheet.

The TDA7491LP 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-down (EPD) package no separate heatsink is required.

Furthermore, the filterless operation allows a reduction in the external component count.

5 W + 5 W continuous output power: RL = 8 Ω, THD = 10% at VCC = 9 V.
5 W + 5 W continuous output power: RL = 4 Ω, THD = 10% at VCC = 6.6 V.
Wide range single supply operation (5 V - 14 V).
High efficiency (η = 90%).
Four selectable, fixed gain settings of nominally 20 dB, 26 dB, 30 dB and 32 dB.
Differential inputs minimize common-mode noise.
Filterless operation.
No ‘pop’ at turn-on/off.
Standby and mute features.
Short-circuit protection.
