The TDA7498E is a dual BTL class-D audio amplifier with a single power supply designed for home systems and active speaker applications. It features wide-range single-supply operation (14-36V), high efficiency (η=85%), parallel BTL function, four selectable, fixed gain settings, differential inputs, standby and mute features, smart protection, thermal overload protection, and small offset less than 20mV.
The TDA7498E is a preliminary product designed as a dual bridge-tied load (BTL) class-D audio amplifier intended for home systems and active speaker applications. It operates from a single power supply in the range of 14 V to 36 V and features a PowerSSO36 package with an exposed pad up (EPU) to facilitate heatsink mounting.
The device provides selectable fixed gain settings via the GAIN pin and includes smart protection mechanisms such as thermal overload, overcurrent, and undervoltage protection. It supports both stereo operation and mono parallel BTL mode using the MODE pin, offering high efficiency of approximately 85%.
| Output power (stereo) | 160 W + 160 W |
|---|---|
| Supply voltage range | 14 - 36 V |
| Efficiency | 85% |
| Gain settings | 23.8 dB, 29.8 dB, 33.3 dB, 35.8 dB |
| Package type | PowerSSO36 (EPU) |
Gain is selected by applying a voltage to the GAIN pin; specific voltages correspond to fixed gains of 23.8 dB, 29.8 dB, 33.3 dB, and 35.8 dB.
The device includes smart protection with thermal overload, overcurrent, undervoltage, and mute/standby functions.
