DESCRIPTION
FEATURES
An integrated stereo Class D/AB speaker driver and Class W headphone driver minimize power consumption during audio playback. Stereo full duplex asynchronous sample rate conversion and multi-channel digital mixing combined with powerful analogue mixing allow the device to support a huge range of different architectures and use cases. A multiband compressor and programmable parametric EQ provide volume maximisation and speaker compensation in the digital playback paths. The dynamic range controller can be used in record or playback paths for maintaining a constant signal level, maximizing loudness and protecting speakers against overloading and clipping. A smart digital microphone interface provides power regulation, a low jitter clock output and decimation filters for up to four digital microphones. Microphone activity detection with interrupt is available. Impedance sensing and measurement is provided for external accessory / push-button detection. Fully differential internal architecture and on-chip RF noise filters ensure a very high degree of noise immunity.
