TDA7498
100-watt + 100-watt dual BTL class-D audio amplifier
Features
100-W + 100-W output power at
THD = 10% with RL = 6 Ω and VCC = 36 V
80-W + 80-W output power at
THD = 10% with RL = 8 Ω and VCC = 34 V
Wide-range single-supply operation (14 - 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
PowerSSO36
with exposed pad up
Description
The TDA7498 is a dual 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.
