Description
LM3886TF Introduction
The LM3886TF is NS has introduced a newtype of high-power audio amplifier IC behind the TF full insulation package(LM3886T heat sink, insulation), and LM1875T its power, the maximum ratedworking voltage up to 68W of continuous distortion of the average power, alsohas a relatively complete overvoltage overcurrent thermal protection function,the most valuable is that it has anti-switch machine automatically when thecurrent shock, so the speaker can safely work. LM3886 excellent performance,making it widely used in sound production in recent years many of the finishedamplifier has a direct application of it as a post-amp or use it as a bass amplifier.This product uses the United States NS (National Semiconductor) has introduceda new high-fidelity audio power amplifier IC the LM3886TF for poweramplification! Its features include: output power (continuous output power of68W), distortion is small (total distortion plus noise <0.03%), protection(including over-voltage protection, thermal protection, current limit,temperature limit, the speaker of the impact of the switching power supplyprotection, mute function) is complete, fewer external components, productiondebugging easy, stable and reliable. Use it to produce power amplifier circuithas a simple, applicable to the characteristics, especially suitable for theproduction of Shaoyou and electronic enthusiasts!
