MAX98090AETL+T

The MAX98090AETL+T is a low-power audio codec from Maxim Integrated used for both input and output of audio signals. It is a single-chip audio codec system with integrated headphone amplifier, integrated low-noise microphone preamplifier and DAC, and wide dynamic range line inputs. It supports single-ended and differential line inputs and output, allowing it to provide a wide dynamic range and high output power. The device also includes integrated switching devices to support multiple application configurations.

The MAX98090AETL+T is suitable for use in applications such as portable media devices, audio amplifiers, home theater systems, distributed audio systems, and automotive applications. Its integrated headphone amplifier and digital to analog converter (DAC) provide a convenient and effective solution for digital audio processing. It can be used for applications such as speakers, headphone, and microphone drives.

In operation, the MAX98090AETL+T operates in an audio CODEC mode that enables its analog front-end to process analog audio signals including microphone input and output signals, as well as digital audio signals from a media player. Its convenient headphone amplifier, low-noise microphone preamplifier and differential line in and line out (with up to 24-bit/96 kHz resolution) make it ideal for a variety of audio-processing applications.

The MAX98090AETL+T works in conjunction with the digital audio interface module in most media devices. This module is responsible for transmitting and receiving audio streams over the digital buses of these devices. The audio streams are then sent to the MAX98090AETL+T, which processes the audio and sends the output to the headphone amplifier. The headphone amplifier then amplifies the audio signal and sends it to the headphone jack.

The device includes an integrated discrete sigma-delta modulator (SDM) which supports up to 24-bit audio input/output up to 96 kHz resolution. The SDM features a feedback path to optimize the conversion performance of the MAX98090AETL+T for maximum dynamic range and low noise. The integrated design of the device reduces the total number of components which is necessary to build an audio solution, thus reducing the cost and complexity.

In addition to its SDM, the MAX98090AETL+T also features integrated two-channel digital-to-analog converter (DAC) and integrated two-channel low noise microphone preamplifier. The DAC supports sampling rate from 8 kHz to 96 kHz and integrated headphone amplifier allows the device to support a wide range of headphone drive levels with low noise. The integrated microphone preamplifier supports up to 80 dB of gain and low noise microphone boost.

One of the advantages of the MAX98090AETL+T is its low power consumption. It is rated for a total power consumption of 0.6 W in a single-supply 5 V load. This low power consumption enables the device to be used in portable audio applications where power is at a premium. It also helps reduce system cost and increase battery life.

Overall, the MAX98090AETL+T is a versatile, low-power audio codec system used for both input and output of audio signals. Its single-supply operation and integrated headphone amplifier, low-noise microphone preamplifier and DAC, and wide dynamic range support make it an ideal solution for a variety of audio-processing applications. Its low power consumption also enables the device to be used in power-sensitive applications.
