The device is equipped with common mode feedback circuitry allowing outputs to be always biased at VCC/2 regardless of the input common mode voltage. The TS4995 is specifically designed for high quality audio applications such as mobile phones and requires few external components. Description The TS4995 is an audio power amplifier capable of delivering 1.2 W of continuous RMS output power into an 8 Ω load at 5 V. Thanks to its differential inputs, it exhibits outstanding noise immunity. An external standby mode control reduces the supply current to less th...
