68W Power Amplifier using LM388668W Power Amplifier using LM3886

The LM3886 is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 4 load and 38W into 8 with 0.1% THD+N from 20Hz-20kHz.


Maximum Output Power : 68W RMS - 108W Peak

THD : %0.03 at 60W

SNR : 110dB at 60 W - 92.5dB at 1W

PSRR : 120dB

Protection circuitries : DC /AC Short circuit protection and thermal protection

Output Class : Conjugate AB-A

The achievement of the LM3886, utilizing its Self Peak Direct Temperature (°Ke) (SPiKe™) aegis circuitry, puts it in a chic aloft detached and amalgam amplifiers by accouterment an inherently, dynamically adequate Safe Operating Area (SOA). SPiKe aegis agency that these genitalia are absolutely safeguarded at the achievement adjoin overvoltage, undervoltage, overloads, including shorts to the supplies, thermal runaway, and direct temperature peaks.

The LM3886 maintains an accomplished signal-to-noise arrangement of greater than 92dB with a archetypal low babble attic of 2.0µV. It exhibits acutely low THD+N ethics of 0.03% at the rated achievement into the rated amount over the audio spectrum, and provides accomplished breadth with an IMD (SMPTE) archetypal appraisement of 0.004%.
