MAX 9835712S 3W AMPILIFITER MODULE

Description

MAX98357 I2S 3W Class D Amplifier Interface Audio Decoder Module Filterless Board For Raspberry Pi ESP32. The I2S digital audio amplifier board accepts digital audio through the I2S interface, converts it to an analog output signal, and amplifies it to allow direct speaker connection. It combines an I2S D / A converter with an audio amplifier on one board. The small stereo amplifier module is surprisingly powerful and delivers up to 3.2W on 4Ω impedance speakers. The class D amplifier can be operated with a voltage of 2.7 V – 5.5 V. Due to the high efficiency of the amplifier, the module is particularly suitable for mobile and battery-powered projects. Filterless Class D Outputs: 77dB PSRR at 1kHz, Low RF Susceptibility Rejects TDMA, Noise from GSM Radios, Extensive Click-and Reduction Circuitry, Robust Short-Circuit and Thermal Protection Specifications : Operating voltage: 2.7 – 5.5 V The I2S audio input supports 3.3V and 5V levels 3.2W output at 10% THD, Speaker Spec : 4 Ω impedance of the speaker and 5 V power supply The stereo signals (L + R) are mixed to form an output signal.
