MAX98357A Series 5.5V 3.2W PCM Input Class D Audio Power Amplifier - TQFN-16 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. Simply supply power, LRCLK, BCLK, and digital audio to generate audio! Furthermore, a novel pinout allows customers to use the cost-effective WLP package with no need for expensive vias (refer to Application Note 6643: Optimize Cost, Size, and Performance with MAX98357 WLP for more information). The digital audio interface is highly flexible with the MAX98357A supporting I2S 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 operate using 16/24/32-bit data for I2S and left-justified modes as well as 16-bit or 32-bit data using TDM mode. The ICs eliminate the need for the external MCLK signal that is typically used for PCM communication. This reduces EMI and possible board coupling issues in addition to reducing the size and pin count of the ICs. 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. The ICs are available in 9-pin WLP (1.345mm x 1.435mm x 0.64mm) and 16-pin TQFN (3mm x 3mm x 0.75mm) packages and are specified over the -40°C to +85°C temperature range. ● 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 ● 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 ● Solution Size with Single Bypass Capacitor is 4.32mm2 Applications ● Single Li-ion Cell/5V Devices ● Smart Speakers ● Notebook Computers ● IoT Devices ● Gaming Devices (Audio and Haptics) ● Smartphones ● Tablets ● Cameras #commonpartslibrary #integratedcircuit #linearamplifier #mono
