Applications
The TDA2052V is primarily used in audio applications such as TV and Hi-Fi systems. It is particularly suitable for multiway speaker systems where it can drive subwoofers, mid-range, and tweeter speakers independently. This configuration helps in reducing the power level required for each individual amplifier, ensures complete separation of the audio signal paths, and protects delicate tweeters from high-power harmonics generated by low-frequency clipping.
