TDA7492MV
50 W mono BTL class-D audio amplifier
Features
50 W continuous output power:
RL = 6 Ω, THD = 10% at VCC = 25 V
40 W continuous output power:
RL = 8 Ω, THD = 10% at VCC = 25 V
Wide range single supply operation (10 - 26 V)
High efficiency (η = 90%)
Four selectable, fixed gain settings of
nominally 21.6 dB, 27.6 dB, 31.1 dB and
33.6 dB
Differential inputs minimize common-mode
noise
Standby and mute features
Short-circuit protection
Thermal-overload protection
Externally synchronizable
PowerSSO-36 with
exposed pad down
Description
The TDA7492MV is a mono BTL class-D audio
amplifier with single power supply designed for
home systems and docking stations.
Thanks to the high efficiency and an
exposed-pad-down (EPD) package no heatsink is
required.
