The LM3876T from Texas Instruments is a high-performance audio power amplifier designed for demanding audio applications. It delivers 56W of continuous average power to an 8 Ohm load with a low Total Harmonic Distortion + Noise (THD+N) of 0.1% from 20 Hz to 20 kHz.
This amplifier utilizes National Semiconductor's SPiKe protection circuitry, providing inherent, dynamic protection for the Safe Operating Area (SOA). This safeguards the output against overvoltage, undervoltage, overloads, shorts to supplies, thermal runaway, and instantaneous temperature peaks. The LM3876T maintains an excellent signal-to-noise ratio greater than 95 dB and exhibits a typical low noise floor of 2.0 µV.
Key electrical specifications include a typical THD+N of 0.06% at 40W into 8 Ohms with a 35V supply, a typical IMD (SMPTE) rating of 0.004%, and a bandwidth of 8 MHz. It operates within a supply voltage range of 24V to 84V, with a nominal supply of 35V. The device also includes an input mute function.
Packaged in a TO-220 through-hole configuration, the LM3876T is suitable for applications such as component stereo systems, compact stereos, self-powered speakers, surround-sound amplifiers, and high-end stereo televisions. Its robust protection features make it a reliable choice for high-fidelity audio designs.
