مميزات خاصة

  • Single-Supply Operation - Operates on 2.5V-5.5V power with 2.4mA quiescent current for battery-powered devices.
  • High-Power Output - Delivers 3.2W into 4Ω at 5V with 92% efficiency (8Ω, 1W), ideal for portable speakers and audio systems.
  • Low Noise Performance - 25µV RMS output noise and 0.015% THD+N at 1kHz ensure crystal-clear sound quality.
  • Filterless Class D Design - Eliminates external output filters with edge-rate control, reducing component count and board space.
  • Flexible Digital Interface - Supports I2S/left-justified/TDM formats with 8kHz-96kHz sample rates for compatibility with ESP32, Raspberry Pi, and microcontrollers.

Product Description
MAX98357 High-Efficiency Filterless Class D Audio Amplifier Module - Crystal-Clear Sound for IoT & Embedded Systems
The MAX98357 Audio Amplifier Module combines Class AB audio quality with Class D efficiency, delivering professional-grade performance in a compact form factor. Engineered for IoT devices, portable speakers, and embedded systems, this module supports digital audio interfaces and advanced protection features.
Key Features:
Dual IC Flexibility: MAX98357A handles I2S data, while MAX98357B supports left-justified data, both with 8-channel TDM capability.
Gain Options: Five selectable gains (3dB-15dB) in I2S/left-justified mode or fixed 12dB in TDM mode via a single pin.
Robust EMI Control: Active edge-rate limiting and spread-spectrum modulation minimize electromagnetic interference.
Wideband Jitter Tolerance: 12ns typical tolerance on BCLK/LRCLK ensures stable operation across varying clock conditions.
Protection Features: Short-circuit, thermal, and click/pop reduction circuitry safeguard against damage.
Technical Specifications:
Output Power: 3.2W (4Ω, 5V) / 2.1W (8Ω, 5V)
Efficiency: 92% at 1W (8Ω)
Supply Voltage: 2.5V-5.5V
Noise: 25µV RMS (A V = 15dB)
Sample Rates: 8kHz-96kHz
Package: 1.345x1.435mm WLP or 3x3mm TQFN
Applications:
Smart speakers and soundbars
Wearable audio devices
Automotive infotainment systems
Industrial audio equipment
Raspberry Pi/ESP32 projects requiring high-fidelity sound
Why Choose MAX98357?
