The STS4890 is a 1.1-W, fully integrated, audio power amplifier. It is designed to maximize audio performance in portable applICations such as mobile phone. The portable application requires audio power amplifier has minimum of external components and can operate from a single 2.5V to 5.5V power supply. TS4890 is capable of delivering 1.1W of continuous output power with less than 1% distortion (THD + N) when it drives an 8Ω speaker from a 5.0V power supply.

The TS4890 features a low-power consumption shutdown mode, which is achieved by driving the shutdown pin with a logic low. Additionally, the TS4890 features an internal thermal shutdown protection mechanism.

The TS4890 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.

For maximum flexibility, the TS4890 provides an externally controlLED gain (with resistors), as well as an externally controlled turn-on time (with the bypass capacitor). When using a 1μF bypass capacitor, it offers 110ms wake up time when V+ is equal to 5.0V.

The TS4890 is available in CSP-9 and MSOP-8 packages. It operates over an ambient temperature range of –40℃ to +85℃.
