特性
- Sophisticated speaker protection and audio boost algorithm running on an embedded CoolFlux®. DSP
- Receiver speaker driver with low noise (12uV A-weighted) and excellent power supply noise rejection (>105dB)
- Support for Smart Receiver driver mode
- Automatically detect speaker issues during the phone manufacturing
- Advanced power management, results in lower average-power consumption than competing solutions
- Intelligent DC-DC boost converter
- Battery monitoring system
- Easy integration into any system design
- PCB size utilization is optimized by reducing the number of external components (boost converter coil for stereo use)
- Multiband dynamic range compressor (DRC) allows independent control of up to three frequency bands
