Add To BomLM4780TA General Description
The LM4780TA is a stereo 60W audio amplifier integrated circuit produced by Texas Instruments. It is designed for high-performance audio applications, offering low distortion and high output power. The LM4780TA features two independent amplification channels, allowing it to drive a stereo speaker system with a maximum output power of 60W per channel.This amplifier IC operates on a wide supply voltage range of ±20V to ±84V, making it suitable for a variety of audio systems. It has a high signal-to-noise ratio of 96dB and a total harmonic distortion of 0.004% at 1kHz, ensuring clear and crisp sound quality.The LM4780TA is equipped with thermal shutdown, overvoltage protection, and short-circuit protection features to prevent damage to the IC and connected components. It also includes a mute function that allows the user to silence the amplifier when needed.The LM4780TA comes in a 27-lead TO-220 package, making it easy to integrate into audio amplifier designs.
