The LM4890MMX is a versatile 1 Watt audio power amplifier manufactured by NS, primarily intended for demanding applications in mobile phones and portable communication devices. It is capable of delivering 1 watt of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5V DC power supply.
This amplifier features a Class-AB input architecture and operates within a wide analog supply voltage range of 2.2V to 5.5V. Key electrical specifications include a typical output power of 1W at 5.0V and 1% THD, and 400mW at 3.3V and 1% THD. It also boasts a low shutdown current of 0.1μA typical and a PSRR of 62dB typical at 217Hz.
The LM4890MMX is designed for ease of use, requiring no output coupling capacitors, snubber networks, or bootstrap capacitors. It includes thermal shutdown protection and an improved pop & click circuitry to eliminate noises during turn-on and turn-off transitions. The device is unity-gain stable and offers external gain configuration capability.
Available in space-saving packages such as VSSOP (DGK) and SOIC (D), the LM4890MMX is suitable for compact designs. Its operating temperature range is from -40°C to 85°C, making it robust for various environmental conditions.
