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.
主な特徴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 dBDifferential inputs minimize common-mode noise
Standby and mute features
Thermal overload protection
