68W Power Amplifier using LM3886
68W Power Amplifier using LM3886features:
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%.
