TDA7491HV
20 W + 20 W dual BTL class-D audio amplifier
Features
20 W + 20 W continuous output power:
RL = 8 , THD = 10% at VCC = 18 V
Wide range single supply operation (5 V - 18 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
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
exposed-pad-down (EPD) package no separate
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.
