Distribution of sound engineering in the ground

In Electronic Infomation Category: D | on April 27,2011

One audio ground distribution of attention to detail

, there are both small signal input circuit, there are large signal output, usually the input and LTC1428CS8-50 datasheet and output delivery by the panel. If the input and LTC1428CS8-50 price and output locations are connected, then make sure they were ground to the public in line with the wire, but can not share a ground wire.

, if the actual circuit of cloth, all levels of the ground component and LTC1428CS8-50 suppliers and more of these components are impossible to penetrate a threading hole, but the level ground component will be as close as possible grounding in the public period or a region can also branch from the ground line or ground leads to ground island.

, ground layout is reasonable or not decided: whether the current in the ground with the current flowing through the independent circuit or components.

, high power audio output stage in the arrangement, the output power block and filter larger components such as electrolytic capacitors to be mounted on-board and to a number of elements which should take place and the level within the circuit board ground component to do a little ground.

, ground to address the allocation should be based on the current, both independent of each other can not be combined with a ground current, allowing the current through a ground land lines can not be separated.

Second, when there are a variety of signaling pathways and output wires to the wiring board, in order to prevent parasitic coupling, should do the following points:

, signal lines should be avoided in the layout by the parallel with each other, especially in dealing with the cross-line and double-sided printing, you should pay attention to both sides of vertical or cross the wire, not equality;

, at all levels between the signal traces as short as possible;

, face plate an equal set of signal conductors of domestic demand, the gap should be possible to make these wires a certain distance, or land lines, power lines are separated to achieve the purpose of shielding; In addition to printed wire

inherent inductance and resistance, the sound in the wires, there are still mutual inductance and capacitance. When the circuit is high frequency or current is large, it will also bring other parts of the interference, we call this parameter as the distribution between the wires due to harmful interference coupling called the parasitic coupling.

, when all levels of circuit arrangement, according to the order of the signal can not bypass or level of arrangement, it can avoid each other at all levels across the signal line between;
