The TDA7498E is a dual BTL class-D audio amplifier with a 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.
The TPA3116D2 is a stereo efficient, digital amplifier power stage for driving speakers up to 100W / 2Ω in mono. The high efficiency of the TPA3130D2 allows it to do 2 × 15 W without an external heat sink on a single layer PCB. The TPA3118D2 can even run 2 × 30 W / 8Ω without a heat sink on a dual-layer PCB, If even higher power is needed the TPA3116D2 does 2 × 50 W / 4 Ωwith a small heatsink attached to its top side PowerPAD. All three devices share the same footprint enabling a single PCB to be used across different power levels.
The TPA3116D2 advanced oscillator/PLL circuit employs multiple switching frequency options to
avoid AM interferences; this is achieved together with an option of either master or slave option, making it possible to synchronize multiple devices.
The TPA3116D2 is fully protected against faults with short-circuit protection and thermal protection as well as overvoltage, Undervoltage, and DC protection. Faults are reported back to the processor to prevent devices from being damaged during overload conditions.
