2 Texas Instruments 68W Low Noise Audio Power Amplifier IC LM3886 / LM3886T NEW
This is a Brand New lot of 2 (Two) National Semiconductor LM3886 who later merged with Texas Instruments High Performance Audio Amplifier Class AB 68W @ 4 Ohms.
This amp is considered one of the better of the integrated TO-220 audio amp packages available today.
You may power your speaker with four Ohms or eight (68W or 38W) from this very compact package that has been rendered all but impossible to damage via the usual means (direct short to leads, rail voltage to leads, overcurrent and overtemp conditions) thanks to TI’s Self protection circuitry called SPiKE.   Signal to noise ratio is a very high 92dB.
