PAMEENCOS 10Pcs MAX98357 I2S Audio Amplifier Module, Audio Amplifiers, Filterless ss D Amplifier, Compatible with ESP32 Raspberry Pi

The MAX98357A/MAX98357B are digital pulse-code modulation (PCM) input Class D power amplifiers that provide Class AB audio performance with Class D effi-ciency. These ICs offer five selectable gain settings (3dB, 6dB, 9dB, 12dB, and 15dB) in I 2 S/left-justified mode set by a single gain select input and a fixed 12dB gain in TDM mode. The digital audio interface is highly flexible with the MAX98357A supporting I 2 S data and the MAX98357B supporting left-justified data. Both ICs support 8 channel time division multiplexed (TDM) data. The digital audio interface accepts specified sample rates between 8kHz and 96kHz for all supported data formats. The ICs can be configured to produce a left channel, right channel, or (left/2 + right/2) output from the stereo input data. The ICs also feature a very high wideband jitter tolerance (12ns typ) on BCLK and LRCLK to provide robust operation. Active emissions-limiting, edge-rate limiting, and overshoot control circuitry greatly reduce EMI. A filterless spread-spectrum modulation scheme eliminates the need for output filtering found in traditional Class D devices and reduces the component count of the solution. Single-Supply Operation (2.5V to 5.5V). 3.2W Output Power into 4I at 5V. 2.4mA Quiescent Current. 92% Efficiency (R L = 8I, P OUT = 1W). 25µV RMS Output Noise (A V = 15dB). Low 0.015% 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. Low RF Susceptibility Rejects TDMA Noise from GSM Radios. Extensive Click-and-Pop Reduction Circuitry. Robust Short-Circuit and Thermal Protection. Available in Space-Saving Packages: 1.345mm x 1.435mm WLP (0.4mm Pitch) and 3mm x 3mm TQFN.
