The LM4780TA from Texas Instruments is a high-fidelity audio power amplifier designed for stereo or mono applications. In stereo mode, it can deliver up to 60W per channel into an 8Ω load with less than 0.5% THD+N. For higher power needs, it can be configured for mono bridge or parallel operation to achieve 120W.
Key features include National's SPiKe protection circuitry, which safeguards the amplifier against over-voltage, under-voltage, thermal runaway, and output shorts. It also incorporates a smooth transition fade-in/out mute function. The amplifier operates over a wide supply voltage range of 20V to 84V and offers a signal-to-noise ratio of at least 97dB.
Applications for the LM4780TA include component stereo systems, compact stereo setups, self-powered speakers, and high-end or HD televisions. Its robust protection features and low external component count make it a versatile choice for audio amplification designs.
The LM4780TA is available in a TO-220 package and is designed for through-hole mounting.
