  • Method and system for adjusting the dynamic range of a digital-to-analog converter in a wireless communications device
    Patent number: 6892177
    Abstract: A wireless communication device (100) may include a receiver (110), a memory (104), a digital-to-analog converter (128), an audio playback system (124) and other features. A dynamic range controller (130) selectively generates control signals to adjust, at least in part, the operational dynamic range of the digital-to-analog converter (128) for digital signals received by the receiver (110) or stored in the memory (104). The selection of dynamic range is based on identifying a characteristic. In one embodiment, the control signals are used to selectively operate the digital-to-analog converter (128) at a particular dynamic range based on a sampling rate of a received digital audio signal.
