TDA7491P  
2 x 10-watt dual BTL class-D audio amplifier  
Features  
10 W + 10 W continuous output power:  
R = 6 Ω, THD = 10% at V = 11 V  
L
CC  
9.5 W + 9.5 W continuous output power:  
R = 8 Ω, THD = 10% at V = 12 V  
L
CC  
Wide range single supply operation (5 V - 18 V)  
High efficiency (η = 90%)  
PowerSSO-36 with  
exposed pad down  
Four selectable, fixed gain settings of  
nominally 20 dB, 26 dB, 30 dB and 32 dB  
Differential inputs minimize common-mode  
noise  
Description  
Filterless operation  
The TDA7491P is a dual BTL class-D audio  
amplifier with single power supply designed for  
LCD TVs and monitors.  
No ‘pop’ at turn-on/off  
Standby and mute features  
Short-circuit protection  
Thermal overload protection  
Externally synchronizable  
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.
