Product Overview: MAX9701EBP+T

The MAX9701EBP+T is a high-performance, mono Class D audio amplifier from Maxim Integrated, designed to deliver high-quality sound with high efficiency. This compact component is ideal for portable applications where space is at a premium and power efficiency is crucial.

Key Features

• High Efficiency: The Class D operation offers more than 90% efficiency, significantly reducing heat dissipation and extending battery life in portable devices.
• Output Power: Capable of delivering 2.4W into a 4Ω load or 1.5W into an 8Ω load, with a 5V power supply, making it suitable for a wide range of audio applications.
• Low EMI: Spread-spectrum modulation and a filterless output reduce electromagnetic interference (EMI), simplifying system design and allowing for the use of smaller, less expensive external components.
• Compact Package: Available in a tiny 20-bump WLP (Wafer-Level Package) or a 20-pin TQFN (Thin Quad Flat No-lead) package, providing flexibility for different design layouts.

Applications

The MAX9701EBP+T is versatile and can be used in a variety of devices, including:

• Mobile Phones
• Tablet Computers
• Portable Media Players
• Handheld Gaming Devices
• GPS Units

Technical Specifications

With a wide supply voltage range from 2.7V to 5.5V, the MAX9701EBP+T is designed to operate over the industrial temperature range of -40°C to +85°C. Additionally, it features a high 73dB PSRR (Power Supply Rejection Ratio) at 217Hz, which minimizes noise transmitted from fluctuating supply voltages.

Additional Features

• Low THD+N: Total Harmonic Distortion plus Noise is minimized, ensuring clear audio reproduction.
• Robust Protection: The device includes built-in thermal overload protection, output short-circuit protection, and under-voltage lockout, enhancing the reliability and lifespan of the amplifier.
• Adjustable Gain: External gain-setting resistors allow for flexible gain configurations, accommodating a range of input sources and output requirements.

Overall, the MAX9701EBP+T from Maxim Integrated is a powerful audio solution for designers looking to balance performance with power efficiency in their compact audio devices.
