Description

The TDA7491HV is designed as one kind of 20 W + 20 W dual BTL class-D audio amplifier with single power supply designed for LCD TVs and monitors. Features of it are:(1)20 W + 20 W continuous output power:RL=8 , THD=10% at VCC=18 V;(2)wide range single supply operation (5 V-19 V);(3)high efficiency (=90%);(4)four selectable, fixed gain settings of 20 dB,26 dB, 30 dB and 32 dB;(5)differential inputs minimize common-mode noise;(6)filterless operation;(7)no 'pop' at turn-on/off;(8)standby and mute features;(9)short circuit protection;(10)thermal overload protection;(11)externally synchronizable.

The absolute maximum ratings of the TDA7491HV can be summarized as:(1)DC supply voltage for pins PVCCA, PVCCB, SVCC:23 V;(2)operating temper-ature:0 to 70 °C;(3)junction temperature:-40 to 150 °C;(4)storage temperature:-40 to 150 °C;(5)thermal resistance, junction to case:2°C/W;(6)thermal resistance, junction to ambient:24°C/W.If you want to know more information such as the electrical characteristics about the TDA7491HV,please download the datasheet in www.seekic.com or www.chinaicmart.com .
