Product Summary

The SN4990WIR1 has been designed for demanding audio applications such as mobile phones and permits the reduction of the number of external components. It is capable of delivering 1.33W of continuous RMS output power into an 8Ω load @ 5 V. An externally-controlled standby mode reduces the supply current to much less than 1μA. SN4990WIR1 also includes internal thermal shutdown protection. The unity-gain stable amplifier can be configured by external gain setting resistors.
