150W LM3886 Power Amplifier


150W LM3886 Power Amplifier


LM3886 power amplifier with 150W audio output power. Three LM3886 amplifiers are bridged together to achieve 150W. Power supply is +/- 30V. LM3886 amplifier maintains an excellent signal-to-noise ratio of greater than 92dB with a typical low noise floor of 2.0µV. It exhibits extremely low THD+N values of 0.03% at the rated output into the rated load over the audio spectrum, and provides excellent linearity with an IMD (SMPTE) typical rating of 0.004%

LM3886 Power Amplifier Features:

Maximum Output Power : 150W

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 performance of the LM3886, utilizing its Self Peak Instantaneous Temperature (°Ke) (SPiKe™) protection circuitry, puts it in a class above discrete and hybrid amplifiers by providing an inherently, dynamically protected Safe Operating Area (SOA). SPiKe protection means that these parts are completely safeguarded at the output against overvoltage, undervoltage, overloads, including shorts to the supplies, thermal runaway, and instantaneous temperature peaks.
