TDA7491LP

TDA7491LP 2 x 5-watt dual BTL class-D audio amplifier 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, 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 overload protection ■ Externally synchronizable PowerSSO-36 with exposed pad down Description 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. The TDA7491LP is pin-to-pin compatible with ...
