... Under-Voltage Protection: Upon system power-up the under-voltage protection circuitry allows the power supplies and their corresponding caps to come up close to their full values before turning on the LM3886 such that no DC output spikes occur. Upon turn-off, the output of the LM3886 is brought to ground before the power supplies such that no transients occur at power-down ...

... Equation (4) and is based on the fact that thermal heat flow parameters are analogous to electrical current flow proper- ties also known that typically the thermal resistance, θ (junction to case), of the LM3886 is 1˚C/W and that using Thermalloy Thermacote thermal compound provides a ther- mal resistance, θ (case to heat sink), of about 0.2˚C explained in the Heat Sinking section ...

... It is advisable to keep the output compensation components and the 0.1 µF supply decoupling capacitors as close as possible to the LM3886 to reduce the effects of PCB trace resistance and inductance. For the same reason, the ground return paths should be as short as possible. ...

... It is hard for most power amplifiers to drive highly capacitive loads very effectively and normally results in oscillations or ringing on the square wave response. If the output of the LM3886 is connected directly to a capacitor with no series resistance, the square wave response will exhibit ringing if the capacitance is greater than about 0.2 µF. If highly ca- ...
