MAX98357 MAX98357A I2S 3W Class DBreakout Interface I2S DAC Decoder

describe: I2S Digital Audio Board, accepts digital audio through the I2S interface, converts it to an analog output signal and it to allow direct speaker connection. It combines an I2S D/A converter and audio on board. Powerful small stereo module delivering up to 3.2W into 4Ω impedance speakers. Class D can operate from 2.7 V - 5.5 V. Due to the high efficiency of the this module is especially suitable for mobile and battery powered projects. The I2S audio input supports 3.3V and 5V levels. The gain can be set to the following values using the gain input: 3dB, 6dB, 9dB, 12dB and 15dB By default, the stereo signal (L + R) is mixed to form the output signal. The behavior can be changed with resistors so that only L or R are output. The module is delivered fully assembled and tested. The delivery includes a pin header and a 2-pin terminal that you can solder on demand. Speakers, leads and breadboard not included. Specification: Output: 3.2 W THD: 10% Speaker Impedance: 4 Ω Power: 5V Operating voltage: 2.7 - 5.5 V 77 dB PSRR at 1 kHz Selectable Gains: 3 dB, 6 dB, 9 dB, 12 dB, 15 dB The package includes: 1pcs * Audio Module notes: 1. Due to manual measurement, please allow 1-3mm error. 2. Due to the difference of different monitors, the picture may not reflect the actual color of the item. Thanks!
