7.1.2 Output Protection

Reactive and EMF-generation loads can return load current to the amplifier, causing the output voltage to exceed the power-supply voltage. This damaging condition can be avoided with clamp diodes from the output terminal to the power supplies, as shown in Figure 7-2. Schottky rectifier diodes with a 3 A or greater continuous rating are recommended.
