TDA7491LP Datasheet (STMicroelectronics) - 2 x 5-watt dual BTL class-D audio amplifier

TDA7491LP, 2 x 5-watt dual BTL class-D audio amplifier

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.

TDA7491LP Features

* 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, 2
