TDA7498MV
100 W mono BTL class-D audio amplifier
Preliminary data
Features
100 W output power at
THD = 10% with RL = 6 Ω and VCC = 36 V
Wide-range single-supply operation (10 - 39 V)
High efficiency (η = 90%)
Four selectable, fixed gain settings of
nominally 25.6 dB, 31.6 dB, 35.1 dB and
37.6 dB
Differential inputs minimize common-mode
noise
Standby and mute features
Short-circuit protection
Thermal overload protection
Externally synchronizable

with exposed pad up
Description
The TDA7498MV is a mono BTL class-D audio
amplifier with single power supply designed for
home systems and active speaker applications.
It comes in a 36-pin PowerSSO package with
exposed pad up (EPU) to facilitate mounting a
separate heatsink.
