ST TDA7498E 160-watt + 160-watt dual BTL class-D audio amplifier handbook
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%.
