A microphone input includes built-in preamp and hardware automatic gain control, with single-ended or fully-differential input capability. The audio output drivers on the ’AIC26 are highly flexible, having software-programmable low or high-power drive modes to optimize system power dissipation. The outputs can be configured to supply up to 325 m W into a bridge terminated 8-Ω load, can support stereo 16-Ω headphone amplifiers in ac-coupled or capless output configurations, and can supply a stereo line-level output A programmable digital audio effects processor enables bass, treble, midrange, or equalization playback processing. The digital audio data format is programmable to work with popular audio standard protocols (I2S, DSP, Left/Right Justified) in master or slave mode, and also includes an on-chip programmable PLL for flexible clock generation capability. Highly configurable software power control is...
