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.The TDA7491P is pin-to-pin compatible with the TDA7491LP and TDA7491HV.
10 W + 10 W continuous output power:RL= 6 O, THD = 10% at VCC = 11 V
9.5 W + 9.5 W continuous output power:RL= 8 O, THD = 10% at VCC = 12 V
Wide range single supply operation (5 V – 18 V)
High efficiency (? = 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
