Maxim Integrated MAX9718AEUB+ Audio Amplifier

The MAX9718AEUB+ is a high-quality, compact audio amplifier from Maxim Integrated, designed to deliver exceptional sound quality with a minimal footprint. This audio amplifier is ideal for portable and space-constrained applications due to its ultra-small, 10-pin µMAX package. It is a perfect solution for adding audio capabilities to a wide range of consumer electronics, including laptops, mobile phones, portable media players, and other devices where space and power efficiency are critical.

Key Features

• Output Power: Capable of delivering 1.4W of continuous output power into a 8Ω load, or 2.3W into a 4Ω load, with less than 1% total harmonic distortion plus noise (THD+N).
• Supply Voltage: Operates from a single 2.7V to 5.5V supply, making it compatible with most battery-operated devices and allowing for flexible design options.
• High Efficiency: Its high-efficiency Class AB output stage ensures extended battery life in portable applications, while also minimizing heat generation.
• Low Quiescent Current: The device features a low quiescent current, further conserving power when in standby mode.
• Comprehensive Protection: Includes built-in thermal overload protection, output short-circuit protection, and click-and-pop suppression to ensure reliable operation and to protect speakers from damage.
• Adjustable Gain: The amplifier's gain can be configured through external gain-setting resistors, providing design flexibility to match specific application requirements.

Applications

The MAX9718AEUB+ is versatile and can be used in a variety of audio applications. Its small size and high efficiency make it particularly well-suited for:

• Portable audio devices
• Mobile phones and tablets
• Laptop computers
• Personal media players
• Portable gaming devices

With its robust feature set and compact design, the MAX9718AEUB+ from Maxim Integrated is an excellent choice for designers looking to enhance the audio experience in their next project while maintaining efficiency and saving space.
