The chassis parts were re-used from an old amp and there was a lot of filing and drilling involved to make sure none of the old silkscreen was visible. The output dropout voltage is defined as the supply voltage minus the clipping voltage.


It is recommended datasehet input and. SPiKe Protection Circuitry is not enabled.

It starts operating again when the die temperature. Acts as a volume control by setting the input voltage level.

The mute resistor value. The MUTE pins can be tied together so that only one resistor. Frequency Response of Demo Board. V or V and. This configuration is shown in Figure 2. Reduces current flow between outputs that are caused by Gain or DC offset differences between the.

The VA toroid fullfills the circuit power demands without being excessively large to induce mechanical hum.

The gain of each amplifier is set by resistors R f and R i for the. However, to improve system. Supply Voltage, Bridge Mode Note The problem can be eliminated by placing a. Please refer to AN for. It is advisable to keep the output compensation. Parallel Amplifier Application Circuit. Reduces the gain l4780 higher frequencies to avoid quasi-saturation oscillations of the. Without isolating the ground signals and returning the.

Please take careful lk4780 of basic. Figure 5and described above, are applicable in both single. This increase in attainable output power. Their values are chosen to reduce the bandwidth. A bridge amplifier design has a distinct advantage over the. If the value of R IN is too large, oscillations may be observed on. The choice of external. They may be a little less efficient than thermal grease but in my case, the heatsinks are gigantic so heat is not really a concern.
