Product Description

TDA7498 Class D Audio Amplifier IC

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.

Key Features

100W + 100W output power at THD = 10% with RL = 6Ω and VCC = 36V
80W + 80W output power at THD = 10% with RL = 8Ω and VCC = 34V
Wide-range single-supply operation (14-39V)
High efficiency (η = 90%)
Four selectable fixed gain settings: 25.6dB, 31.6dB, 35.1dB, 37.6dB
Differential inputs minimize common-mode noise
Standby and mute features
Short-circuit and thermal overload protection
Externally synchronizable
