Detailed explanation of 8002 power amplifier chip
The NS8002 is an audio power amplifier with two OTL circuit Bridges connected in BTL mode. The maximum output power is 3W, the minimum output is 1.5W. The operating voltage is 2-5.5V, which is very suitable for low-voltage electronic products powered by battery or USB. As a power amplifier, it saves the bootstrap circuit and vibration suppression circuit of traditional power amplifier.
Therefore, only a few peripheral components (at least four components) can be operated, and the output does not require external coupling capacitors or bootstrap capacitors and buffering networks
