The LM4905MM/NOPB is an integrated audio amplifier solution produced by Texas Instruments. Designed for portable devices, this amplifier is capable of delivering 1.2W of continuous average power to a 8Ω load with less than 1% distortion (THD+N) from a 5V DC power supply.

Key Features

• Output Power: Delivers 1.2W into 8Ω at 5V.
• High Efficiency: Offers more than 85% efficiency, making it ideal for battery-powered devices.
• Low Quiescent Current: Conserves power with a low shutdown current of 0.1µA, extending battery life.
• Thermal Shutdown Protection: Enhances reliability and longevity with built-in thermal protection.
• Unity-Gain Stable: Can be configured by external gain-setting resistors.

Applications

The LM4905MM/NOPB is suitable for a variety of applications, particularly where space and power efficiency are critical. Common applications include:

• Mobile Phones
• Portable Media Players
• Handheld Gaming Consoles
• PDAs and Portable Organizers
• Notebook Computers

Quality and Reliability

As with all Texas Instruments products, the LM4905MM/NOPB is manufactured to high standards of quality and reliability. The "NOPB" suffix indicates that this product is part of TI's eco-friendly "Green" product initiative, with a lead-free finish and RoHS compliance, reflecting TI's commitment to environmental sustainability.

Package and Availability

The LM4905MM/NOPB comes in a compact 8-pin VSSOP (MSOP) package, which is ideal for space-constrained applications. For design flexibility, it is also available in a variety of bulk and reel quantities to meet production requirements.
