10W+10W雙BTL D類音頻放大器

The TDA7491P is a dual BTL class-D audio amplifier with single power supply designed for LCD TVs and monitors.\n\n Thanks to the high efficiency and exposed-pad-down (EPD) package no separate heatsink is required.\n\n Furthermore, the filterless operation allows a reduction in the external component ? 10 W + 10 W continuous output power:RL= 6 Ω, THD = 10% at VCC = 11 V \n? 9.5 W + 9.5 W continuous output power:RL= 8 Ω, THD = 10% at VCC = 12 V \n? Wide range single supply operation (5 V - 18 V) \n? High efficiency (η = 90%) \n? Four selectable, fixed gain settings of nominally 20 dB,;
