lm3886 pdf

 The LM3886 is a high-performance audio power amplifier

capable of delivering 68W of conTInuous average power to a

4Ω load and 38W into 8Ω with 0.1% (THD + N) from

20 Hz–20 kHz.

The performance of the LM3886, uTIlizing its Self Peak In-

stantaneous Temperature (˚Ke) (SPiKe™) ProtecTIon Cir-

cuitry, puts it in a class above discrete and hybrid amplifiers

by providing an inherently, dynamically protected Safe Oper-

aTIng Area (SOA). SPiKe Protection means that these parts

are completely safeguarded at the output against overvolt-

age, undervoltage, overloads, including shorts to the sup-

plies, thermal runaway, and instantaneous temperature

peaks.

The LM3886 maintains an excellent Signal-to-Noise Ratio of

greater than 92 dB with a typical low noise floor of 2.0 µV. 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 rat-

ing of 0.004%.
