Maxim Integrated's MAX9850ETI+-ND Audio Codec

The MAX9850ETI+-ND is a high-performance, low-power stereo audio codec from Maxim Integrated, designed to deliver exceptional sound quality for a wide range of applications. This integrated circuit is a perfect solution for portable electronic devices where space is at a premium and power efficiency is crucial.

This versatile codec features a 2Vrms stereo line-level output and a high-fidelity audio DAC with 100dB signal-to-noise ratio (SNR), ensuring crystal-clear audio playback. The MAX9850ETI+-ND supports a variety of audio data interfaces, including I²S, left-justified, and DSP formats, providing flexibility for integration with different microcontrollers or digital signal processors.

With its integrated headphone amplifier, the MAX9850ETI+-ND can drive a 16Ω load with ease, making it suitable for use in personal media players, smartphones, tablets, and other portable devices that require high-quality audio output. The headphone amplifier also features a cap-less output, which reduces the need for external components and simplifies the design process.

The device operates over a wide 2.7V to 3.6V supply voltage range and includes an onboard PLL to generate the required audio clock from a variety of input sources. This functionality allows the codec to be used in systems without a dedicated audio clock, further reducing the overall component count and system complexity.

Maxim Integrated has designed the MAX9850ETI+-ND with power management in mind. The codec features low-power shutdown modes and an efficient, class-AB headphone amplifier that minimizes power consumption during operation. This makes it an excellent choice for battery-powered devices where extending the battery life is essential.

The MAX9850ETI+-ND is available in a compact, 28-pin thin QFN package, making it a space-saving solution for modern electronic devices. It is also fully specified over the -40°C to +85°C extended temperature range, ensuring reliable performance in a variety of environments.

With its high SNR, low power consumption, and flexible integration options, the MAX9850ETI+-ND from Maxim Integrated stands out as a superior audio codec solution for designers looking to enhance the audio experience in their next project.
