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.
