Additional preview pages of the TDA7491MV datasheet.

The TDA7491MV is a mono BTL class-D audio amplifier with single power supply designed for LCD TVs and monitors.

Thanks to the high efficiency and an exposed-pad-down (EPD) package no heatsink is required.

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

20 W continuous output power: RL = 8 , THD = 10% at VCC = 18 V.
25 W continuous output power: RL = 6 , THD = 10% at VCC = 16 V.
Wide range single supply operation (5 V - 18 V).
High efficiency ( = 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.
Thermal o.
