The TDA7491HV 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.The TDA7491HV is pin-to-pin compatible with the TDA7491P and TDA7491LP.
20 W + 20 W continuous output power: RL= 8 O, THD = 10% at VCC = 18 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
No ‘pop’ at turn-on/off
Standby and mute features
Short-circuit protection
Thermal overload protection
Externally synchronizable
