TDA7498E vs. TPA3116D2: Which one is better?
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.
