Speaker Protected LM3886TF Stereo Amplifier Circuit

LM3886TF Amplifier circuit pretty a quality PCB design has to supply the diode bridge and filter on the capacity also for the volume control stereo 100k potentiometer attached LM3886 inputs and outputs used in this opamp NE5532 instead ad827 used opamp beslemesiç the same pcb on the 7815 and 7915 fixed regulator IC supply with available the coils are given the values ​​in the output section

LM3886TF plastic sheath used in practice, but the sound quality is a bit low power metal sheath is said to be better than you can use instead LM3886T performance would be better if you can connect to the cooler fan

LM3886TF Stereo Amplifier Project

LM3886TF the United States launched the great merit NS rate audio amplification IC, the TF for the whole behind the insulation package is installed When loose will not come together with the mica insulation film, in the rated working voltage up to 68W of continuous average power is not distorted, Has a relatively perfect over-voltage, over-power flow, over-temperature protection features, the most valuable is its automatic anti-aircraft at the time of switch

LM3886TF Amplifier Circuit Characteristics

LM3886 at VCC = VEE = 28V, 4 in Europe to achieve load of 68W continuous average power, in the VCC = VEE = 35V, 8 Ohm, the load can be achieved when the average power of 50W. Has a wide range of supply voltage VCC + VEE for 20V-94V; Total harmonic distortion + noise ︰ 60W 20Hz <20kHz AV = 26dB, when the value of 0.03% Speed conversion rate (SLEW RATE): VIN = 2.0VP-P, tRISE = 2ns when the value of 19V/us The total static power flow ︰ 50mA Enter the partial flow 0.2uA ︰ Gain-bandwidth product: 8 MHZ
