MAX98357 I2S Amp

The MAX98357 I2S Amp is a board I/O module in the LabWired part catalog. Its catalog type is max98357. It connects to the MCU over GPIO. The catalog gives a supply range of 2.5–5.5 V. It has 9 pins. This part is its pins. There is no separate device model because the MCU’s own GPIO/PWM/ADC model already is the simulation.

From the catalog: I²S pads are digital; audio DAC/speaker not modelled.

How to simulate the MAX98357 I2S Amp in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the MAX98357 I2S Amp (catalog type max98357).
  3. Connect VIN and GND to the supply and ground of the board. Use a supply inside the catalog range of 2.5–5.5 V.
  4. Connect BCLK, LRC, DIN and SD to free GPIO pins.
  5. Connect GAIN, SPEAKER+ and SPEAKER- as your circuit needs.
  6. Run the firmware. It reads and drives these pins through the GPIO, PWM and ADC models of the MCU. The part has no separate device model.
