TDA7491P - 2 x 10-watt dual BTL class-D audio amplifier

Description

The TDA7491P 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.

Features

  • 10 W + 10 W continuous output power: RL = 6 Ω, THD = 10% at VCC = 11 V 9.5 W + 9.5 W continuous output power: RL = 8 Ω, THD = 10% at VCC = 12 V Wide range single supply operation (5 V - 18 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-circu.
