General Description

The MAX98357A/MAX98357B is an easy-to-use, low-cost, digital pulse-code modulation (PCM) input Class D amplifier that provides industry-leading Class AB audio performance with Class D efficiency.

The digital audio interface automatically recognizes up to 35 different PCM and TDM clocking schemes which eliminates the need for I2C programming.

Operation is further simplified by eliminating the need for an external MCLK signal that is typically used for PCM communication.

Key Features

Single-Supply Operation (2.5V to 5.5V).
3.2W Output Power into 4Ω at 5V.
2.4mA Quiescent Current.
92% Efficiency (RL = 8Ω, POUT = 1W).
22.8μVRMS Output Noise (AV = 15dB).
Low 0.013% THD+N at 1kHz.
No MCLK Required.
Sample Rates of 8kHz to 96kHz.
Supports Left, Right, or (Left/2 + Right/2) Output.
Sophisticated Edge Rate Control Enables Filterless Class D Outputs.
77dB PSRR at 1kHz.
