AX5689 Audio Controller

Monolithic Power Systems AX5689 4-channel, digital-input Class-D audio controllers are available in a QFN-64 package

Image of MPS AX5689 Audio Controllers The AX5689 from MPS is a 4-channel bridge-tied load (BTL) or 2-channel parallel bridge-tied load (PBTL) audio controller IC with digital inputs, integrated low-latency analog-to-digital converters (ADCs), and CMOS-level pulse-width modulation (PWM) outputs. It enables high-order digital control loops with post-filter feedback for low power consumption and exceptional audio performance. It is available in a QFN-64 (9 mm x 9 mm) package.

Features
  • 8 flexible, differential low-latency ADCs
  • 8 configurable, digital control loop filter slices
  • 8 CMOS-level PWM outputs
  • Up to 4x BTL channels, 2x 4-phase PBTL channels, or a combination thereof
  • 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
  • Active loudspeakers (party boxes, monitor speakers)
  • Streaming audio amplifier solutions
  • Soundbars and subwoofers
  • Professional audio solutions
  • Thermally sensitive audio solutions
