💎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.
