The TC6871 is a single‑channel audio power amplifier designed for portable devices. It operates from a 2.0 V to 5.5 V supply and can deliver up to 4 W into a 3 Ω load with THD below 10 %.
The device includes a shutdown pin for ultra‑low standby current (0.6 µA typical) and integrates internal bias and feedback networks, eliminating the need for external components. It is supplied in a compact SOP‑8 package and supports external gain setting via a resistor network. This manual is written in Japanese.
