TDA7491LP
2 x 5-watt dual BTL class-D audio amplifier
Features
â 5 W + 5 W continuous output power:
RL = 8 Ω, THD = 10% at VCC = 9 V
â 5 W + 5 W continuous output power:
RL = 4 Ω, THD = 10% at VCC = 6.6 V
â Wide range single supply operation (5 V - 14 V)
â High efficiency (η = 90%)
â Four selectable, fixed gain settings of
nominally 20 dB, 26 dB, 30 dB and 32 dB
â Differential inputs minimize common-mode
noise
â Filterless operation
â No âpopâ at turn-on/off
â Standby and mute features
â Short-circuit protection
â Thermal overload protection
â Externally synchronizable
PowerSSO-36 with
exposed pad down
Description
The TDA7491LP 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 TDA7491LP is pin-to-pin compatible with the
TDA7491P and TDA7491HV.
