Monolithic Power Systems (MPS) AX5688 Digital-Input Class-D Audio Controllers

Monolithic Power Systems (MPS) AX5688 Digital-Input Class-D Audio Controllers offer 2-channel bridge-tied load (BTL) or 1-channel parallel bridge-tied load (PBTL) operation with digital inputs, low-latency ADCs, and CMOS-level PWM outputs. Monolithic Power Systems (MPS) AX5688 controllers support high-order digital control loops with post-filter feedback for low power consumption and excellent audio quality. The ICs come in a 9mm x 9mm QFN-64 package.

Features

  • 4x flexible, differential low-latency analog-to-digital converters (ADCs)
  • 8x configurable, digital control loop filter slices
  • 4x CMOS-level pulse-width modulation (PWM) outputs
  • 2x (BTL) channels or 1x 4-phase (PBTL) channel
  • Feedback is taken after the output filter to reduce distortion
  • Multiple ADCs can be placed in parallel for higher performance
  • Configurable interconnections between slices and ADCs for versatility and multiple input, multiple output (MIMO) control
  • I2C and SPI control interface with selectable address for multi-chip systems

Applications

  • Streaming audio amplifier solutions
  • TV sound-bars, audio entertainment solutions
  • Active loudspeakers
  • High-performance DAC solutions
  • High-resolution low-latency ADC solutions
