Monolithic Power Systems (MPS) AX5689 Digital-Input Class-D Audio Controllers
Monolithic Power Systems (MPS) AX5689 Digital-Input Class-D Audio Controllers offer 4-channel bridge-tied load (BTL) or 2-channel parallel bridge-tied load (PBTL) configurations. The Monolithic Power Systems (MPS) AX5689 controllers feature digital inputs, integrated low-latency analog-to-digital converters (ADCs), and CMOS-level pulse-width modulation (PWM) outputs. The devices are designed for high-order digital control loops with post-filter feedback and deliver low power consumption and excellent audio performance. The controllers come in a 9mm x 9mm QFN-64 package.
Features
- 8x flexible, differential low-latency analog-to-digital converters (ADCs)
- 8x configurable, digital control loop filter slices
- 8x CMOS-level pulse-width modulation (PWM) outputs
- Up to 4x bridge-tied load (BTL) channels, 2x 4-phase parallel bridge-tied load (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
- Streaming audio amplifier solutions
- TV sound-bars, audio entertainment solutions
- Active loudspeakers
- High-performance DAC solutions
- High-resolution low-latency ADC solutions
