MAX98926EWV+T integrated audio amplifier by Maxim Integrated provides high fidelity, high-efficiency audio amplification. This device is a low power audio amplifier combining a class G digital adaptive bi-quad feedback topology amplifier configuration with low noise, low distortion and high power supply rejection ratio (PSRR). This device also offers a wide range of audio-specific features. In this article, we will look at MAX98926EWV+T application field, working principle and its features.

Application Field

MAX98926EWV+T integrated audio amplifier is designed for the following audio applications:

• Portable audio devices
• Speakers
• Communication systems
• Recording systems

Working Principle

The working principle of MAX98926EWV+T integrated audio amplifier is based on the principle of bi-quad feedback topology. This device uses two input signals, one for the left channel and one for the right channel. When the two input signals are applied to the amplifier, the output signal is generated by subtracting the two input signals. The bi-quad feedback topology ensures an accurate control of the output signal by comparing the two input signals and generating a control signal to balance the two input signals. The control signal is then fed back to the input stages to adjust the two signals relative to each other and to achieve the desired output.

Features

The MAX98926EWV+T integrated audio amplifier includes a wide range of features and benefits, such as:

• Class G Digital Adaptive bi-quad feedback topology for improved power efficiency and fidelity
• Integrated temperature management feature for improved thermal performance
• Low noise and low distortion
• High PSRR for improved noise immunity
• Auxiliary outputs for improved flexibility
• Low power consumption for improved battery life
• Compact size for easy integration
