The TS4890 is an audio power amplifier capable of delivering 1W of continuous RMS output power into an 8Ω load. It operates from a voltage range of 2.2V to 5.5V and features ultra-low standby power consumption, low distortion, and pop and click reduction circuitry.
The TS4890 is a rail-to-rail output audio power amplifier capable of delivering 1W of continuous RMS output power into an 8Ω load at 5V. It is designed for high-quality audio applications such as mobile phones and portable audio devices, minimizing the number of external components required. The device features an external standby mode control that reduces supply current to less than 10nA and includes internal thermal shutdown protection.
