LM4889MM Description

Short technical summary and product information.

The LM4889MM from Texas Instruments is a Class-AB audio power amplifier designed for demanding applications in mobile phones and portable communication devices. It is capable of delivering up to 1.2W of output power into an 8Ω load.

Key electrical specifications include a wide operating supply voltage range of 2.2V to 5.5V, with typical power output of 1W at 5.0V and 2% THD, or 400mW at 3.3V and 1% THD. The amplifier exhibits low total harmonic distortion plus noise (THD + N) of 0.1% at 1kHz.

This device features an ultra-low current shutdown mode, consuming only 0.01µA at 3.3V to 2.6V. It includes improved pop and click circuitry to eliminate noise during turn-on and turn-off transitions. The LM4889MM is unity-gain stable and offers external gain configuration capability. It can drive capacitive loads up to 500 pF and does not require output coupling capacitors, snubber networks, or bootstrap capacitors.

The LM4889MM is available in space-saving packages such as VSSOP and SOIC, suitable for surface mount applications.
