The Shenzhen Nsiway Tech NS8002 is a single-channel Class AB audio power amplifier designed for low-voltage audio applications. It operates within a 3.0V to 5.25V supply range and features a bridge-tied-load (BTL) output configuration for efficient audio amplification.

With a simple application circuit and minimal external components, the NS8002 helps simplify audio system design. It does not require external output coupling capacitors, bootstrap capacitors, or snubber networks. The amplifier also supports an active-high shutdown function to reduce power consumption when audio output is not required.

Housed in a compact SOP-8 package, the NS8002 is suitable for portable electronics, computers, and other low-voltage audio systems.
