TDA7498：100W+100W dual BTL Class-D audio amplifier
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
- 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
