TDA7498E
160-watt + 160-watt dual BTL class-D audio amplifier
Preliminary data
Features
■ 160-W + 160-W output power at
THD = 10% with RL = 4 Ω and VCC = 36 V
■ 1 x 220 W output power mono parallel BTL at
THD = 10% with RL = 3 Ω and VCC = 36 V
■ Wide-range single-supply operation (14 - 36 V)
■ High efficiency (η = 85%)
■ Parallel BTL function using the MODE pin
■ Four selectable, fixed gain settings of
nominally 23.8 dB, 29.8 dB, 33.3 dB and
35.8 dB
■ Differential inputs minimize common-mode
noise
■ Standby and mute features
■ Smart protection
■ Thermal overload protection
■ Small offset less than 20 mV

Description
The TDA7498E is a dual BTL class-D audio
amplifier with a 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.
