The LM4889MMX from Texas Instruments is a mono, Class-AB audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication devices. It is capable of delivering up to 1.2 watts of continuous average power to a load.
Key electrical specifications include an analog supply voltage range of 2.2V to 5.5V, with a power stage supply also ranging from 2.2V to 5.5V. The amplifier exhibits a typical THD + N of 0.1% at 1 kHz into an 8Ω load. It can deliver 1.0W typical power output at 5.0V and 2% THD, or 400mW typical power output at 3.3V and 1% THD. The device features an ultra-low current shutdown mode, consuming only 0.01µA typical at 3.3V to 2.6V.
Designed for ease of use, the LM4889MMX operates from 2.2V to 5.5V and does not require output coupling capacitors, snubber networks, or bootstrap capacitors. It is unity-gain stable with external gain configuration capability. The amplifier also includes improved pop and click circuitry to eliminate noises during turn-on and turn-off transitions and can drive capacitive loads up to 500 pF.
Available in space-saving packages such as VSSOP and SOIC, the LM4889MMX is suitable for compact designs. Its operating temperature range is -40°C to 85°C, making it robust for various environmental conditions.
