MAX98357A/ Tiny, Low-Cost, PCM Class D Amplifier with MAX98357B Class AB Performance General Description Features The MAX98357A/MAX98357B is an easy-to-use, low-cost, Single-Supply Operation (2.5V to 5.5V) digital pulse-code modulation (PCM) input Class D ampli- 3.2W Output Power into 4 at 5V fier that provides industry-leading Class AB audio perfor- 2.4mA Quiescent Current mance with Class D efficiency. The digital audio interface 92% Efficiency (R = 8, P = 1W) L OUT automatically recognizes up to 35 different PCM and TDM 2 22.8V Output Noise (A = 15dB) clocking schemes which eliminates the need for I C pro- RMS V gramming. Operation is further simplified by eliminating Low 0.013% THD+N at 1kHz the need for an external MCLK signal that is typically used No MCLK Required for PCM communication. Simply supply power, LRCLK, Sample Rates of 8kHz to 96kHz BCLK, and digital audio to generate audio Furthermore, Supports Left, Right, or (Left/2 + Right/2) Output a novel pinout allows customers to use the cost-effective WLP package with no need for expensive vias (refer Sophisticated Edge Rate Control Enables to Application Note 6643: Optimize Cost, Size, and Filterless Class D Outputs Performance with MAX98357 WLP for more information). 77dB PSRR at 1kHz The digital audio interface is highly flexible with the Low RF Susceptibility Rejects TDMA 2 MAX98357A supporting I S data and the MAX98357B Noise from GSM Radios supporting left-justified data. Both ICs support 8 channel Extensive Click-and-Pop Reduction Circuitry time division multiplexed (TDM) data. The digital audio Robust Short-Circuit and Thermal Protection interface accepts specified sample rates between 8kHz and 96kHz for all supported data formats. The ICs can Available in Space-Saving Packages: be configured to produce a left channel, right channel, or 1.345mm x 1.435mm WLP (0.4mm Pitch) (left/2 + right/2) output from the stereo input data.
