TDA7492MV

50 W mono BTL class-D audio amplifier
Datasheet - production data
Features
50 W continuous output power: RL = 6 ,
THD = 10% at VCC = 25 V 40 W continuous output power: RL = 8 ,
THD = 10% at VCC = 25 V Wide range single supply operation (10 - 26 V) High efficiency ( = 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
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.
