💎Maxim announces the MAX98357 digital input Class D audio power amplifiers, enabling designers to implement compact, efficient plug-and-play solutions at a cost-effective price.In addition to its small form factor, the device is capable of achieving a 3.2W Class AB amplifier with Class D amplifier efficiency, resulting in excellent high fidelity sound for a variety of product applications.The MAX98357 Pulse Code Modulation (PCM) plug-and-play speaker amplifiers take advantage of the flexibility of Maxim's pinout. 35 different clocks and 128 digital audio formats can be automatically configured with a single power supply.For superior sound quality, the device uses a high noise immunity digital input with high jitter tolerance. It also provides excellent electromagnetic interference suppression, allowing long-line connected speakers without the need for external filtering.Suitable for microcontrollers or development board systems with I2S audio output such as Raspberry Pi, Arduino and ESP32.【Pin】LRC: Frame clock. Left/Right clock for I2S and LJ modes. Sync clock for TDM mode.BCLK: Bit clock input.DIN: Digital input signal.GAIN: Gain and channel selection.SD: Shutdown and channel selection. Pull SD_MODE low to place the device in shutdown.GND: Power ground.VCC: DC 2.5V-5.5V.【Features】⚡Output power: 3.2W at 4Ω, THD is 10%; 8Ω is 1.8W, THD is 10%VCC: DC 2.5V-5.5V.Class D amplifier with optional gain: 3dB/6dB/9dB/12dB/15dB12S sampling rate: 8Khz~96KhzPlug and Play: Only a single power supply is needed to automatically configure 35 different clocks and 128 digital audio formatsNo master clock (MCLK) requiredSuitable for Raspberry Pi, Arduino and ESP32 microcontrollers or development board systems with I2S audio output
