The MAX98360A/B/C/D 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 different PCM and TDM clocking schemes which eliminates the need for I2C programming. 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.The digital audio interface is highly flexible. The devices support I2S, left-justified, and 8-channel time division multiplexed (TDM) data formats. The digital audio interface accepts 8kHz, 16kHz, 32kHz, 44.1kHz, 48kHz, 88.2kHz, and 96kHz sample rates. Data words can be 16-bit, 24-bit, or 32-bit in I2S and left-justified modes and 16-bit or 32-bit in TDM mode.Digital audio interface input thresholds are ideal for interfacing to 1.2V and 1.8V logic. The devices can tolerate logic input voltages up to 5.5V.The MAX98360A and MAX98360B have fast 1ms turn-on times while the MAX98360C and MAX98360D ramp the volume over 13ms during turn-on and turn-off.The devices 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. The devices 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 devices are specified over the -40°C to +85°C temperature range.MAX98360 Version ManagementRampingFrame Sync Pulse on LRCLK50% Duty Cycle on LRCLKTurn-On/Off RampStart-Up TimeFormatBCLK Active EdgeFormatBCLK Active EdgeMAX98360ARamp Disabled1msTDMrisingI2SrisingMAX98360BRamp Disabled1msTDMfallingLJrisingMAX98360CRamp Enabled13msTDMrisingI2SrisingMAX98360DRamp Enabled13msTDMfallingLJrisingApplicationsSingle Li-ion Cell/5V DevicesSmart SpeakersNotebook ComputersIoT DevicesGaming Devices (Audio and Haptics)SmartphonesTabletsCameras
