MAX98357AETE+T Audio Power Amplifier SMD IC

MAX98357AETE+T Audio Power Amplifier SMD IC

The MAX98357AETE+T is a digital audio power amplifier that accepts a digital audio input (I2S) and drives a low-impedance speaker. It is a class D amplifier, which means it operates efficiently with minimal heat dissipation compared to traditional analog amplifiers. The IC features an integrated PWM (pulse-width modulation) stage for driving speakers and converting the digital input into an audio signal that can be used by speakers.

DNA solutions, Nashik has various types of Amplifier IC's. Check out our complete collection of Amplifier IC's.

• Class D Output Stage: Provides high efficiency (up to 92%) and low heat dissipation, ideal for battery-powered applications

• Digital Audio Input (I2S): Supports the I2S digital audio interface, which is commonly used in modern audio devices for efficient transmission of stereo audio data

• Integrated Low-Pass Filter: Reduces output noise and ripple, improving audio fidelity by smoothing the PWM signal
