Description
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 slug-down package no heatsink is required. Furthermore, the filterless operation allows a reduction in the external component count. The TDA7491HV is pin to pin compatible with the TDA7491P and TDA7491LP.
Features
20 W + 20 W continuous output power:
RL= 8 ?, THD = 10 at VCC = 18 V
Wide range single supply operation (5 V - 19 V)
High efficiency (η= 90)
Four selectable, fixed gain settings of 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
