LM4890MX Description

Short technical summary and product information.

The LM4890MX from Texas Instruments is a versatile 1 Watt audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication devices. It is capable of delivering 1 watt of continuous average power to an 8 Ohm BTL load with less than 1% distortion (THD+N) from a 5V DC power supply. This amplifier is part of the Boomer audio power amplifier family, engineered to provide high-quality output power with a minimal number of external components.

 

Key features include ultra-low current shutdown mode, BTL output capable of driving capacitive loads, and improved pop and click circuitry to eliminate noises during transitions. It operates within a voltage range of 2.2V to 5.5V and does not require output coupling capacitors, snubber networks, or bootstrap capacitors, simplifying circuit design. The device also includes thermal shutdown protection and is unity-gain stable with external gain configuration capability.

 

The LM4890MX is available in a space-saving SOIC package with 8 pins, suitable for surface mount applications. It operates over an industrial temperature range of -40°C to 85°C. The standard package quantity is 2500 units on tape and reel.
