With the inclusion of two 3.3V analog inputs and two 6V analog outputs, along with an integrated amplifier, it offers a wide range of benefits. Additionally, the device offers an extended range of features and functions, including a low noise microphone pre-amp, low noise amplifier, an adjustable low-distortion limiter, a dedicated line-out, and a high-definition stereo headphone amplifier.

Introduction to the MAX98091ETM+

The MAX98091ETM+ is a low-voltage single-chip audio codec, with integrated power inputs for a wide range of audio applications. It supports the stereo 8-Channel format, which allows for a single device to be used to drive up to 8 separate audio streams. Additionally, it provides wide-range support for sampling rates between 8kHz and 96kHz and output formats from 16-bit PCM to 24-bit PCM (8.24). Coupled with the 10-bit digital-to-analog converter, it offers outstanding audio reproduction and has excellent power management.

Application field of MAX98091ETM+

The MAX98091ETM+ is a great choice for many applications such as mobile phones and portable multimedia applications, high-end consumer amplifiers, sound systems and industrial applications. Additionally, it is suitable for automotive applications, gaming consoles, home entertainment systems, and high-fidelity products. Furthermore, the device enables hands-free calling, on-screen volume adjustment, microphone equalization, dual-source muting capabilities, and low-power mode.

Working Principle of MAX98091ETM+

The MAX98091ETM+ receives data from the stereo 8-Channel digital audio input, which is then converted to an analog signal through a high-performance 8-bit digital-to-analog converter. Once the digital audio data is converted to an analog signal, it is then amplified by an onboard low-noise amplifier. The output signal is then routed to either the integrated line-out, headphone jack, or both for playback purposes.

The device also includes a microphone pre-amp, which is responsible for amplifying signals from a microphone before they are converted to digital audio. This is achieved through the use of a 14-bit analog-to-digital converter, which is connected to the left and right audio input lines. Additionally, the device features an adjustable low-distortion limiter, which is designed to help reduce distortion and minimize noise at the output.

Conclusion

The MAX98091ETM+ is a versatile and powerful integrated audio codec, designed for a wide range of applications. Equipped with two 3.3V analog inputs and two 6V analog outputs, as well as an integrated amplifier, it offers an extensive range of features and functions. With its array of features and functions, it is suitable for a wide range of applications, from mobile devices to automotive products. Furthermore, with its 10-bit digital-to-analog converter and adjustable low-distortion limiter, the MAX98091ETM+ delivers outstanding audio reproduction and has excellent power management.
