We often use or see voice equipment products in our life. These voice products may fail to make sound or the sound becomes intermittent after being used for a long time. These may be the problems of the voice chip inside, and the aging of the voice chip is one of the reasons for the above faults. So what are the general reasons for the aging of voice chips?

First, the internal reason may be

▲ the use of voice products for a long time makes the voice chip aging and can no longer run.

▲there is a problem with the quality of the voice chip used

The reasons for outsourcing are as follows:

▲the user operates improperly, uses a large current, and the working voltage is too high or unstable, resulting in the aging of the voice chip. Generally speaking, the power supply of the operational amplifier is low, generally 2.8V ~ 5.5V.

▲external force damage

▲the working temperature is too high, and the temperature is too high or too long when welding or IC patch

▲power pulse when the power supply is affected (static electricity, lightning strike, power failure)

The above is the reason for the aging of the voice chip. When we use the voice chip, we need to operate correctly to avoid the aging of the voice chip caused by external factors.
