Carefully select external components (such as inputs and negative feedback capacitors) and load
components (such as speakers), for example, power amp and regulator.
If there is a large amount of leakage current such as input or negative feedback condenser, the IC
output DC voltage will increase. If this output voltage is connected to a speaker with low input
withstand voltage, overcurrent or IC failure can cause smoke or ignition. (The over current can cause
smoke or ignition from the IC itself.) In particular, please pay attention when using a Bridge Tied
Load (BTL) connection type IC that inputs output DC voltage to a speaker directly.
