In the imported electronic equipment, you can often see a diagram with positive and negative power, supply power to the op amp circuit manifold. Features: 1. Convenient to make or select the power transformer, the secondary winding of the transformer needs no center tap. 2. Positive and negative power supply voltage symmetry. 3. Energy utilization is higher. 4. Structure is simple. Practice has proved that: the power transformer under the premise of sufficient power capacity, appropriate to increase capacitance and the transformer secondary winding wire, the circuit can also be used for low-power audio amplifier for the positive and negative symmetrical dual supply.
