TLV320DAC26 具有耳机/扬声器放大器的低功耗立体声音频 DAC
TLV320DAC26 描述
The TLV320DAC26 is a high-performance audio DAC with 16/20/24/32-bit 97-dBA stereo playback. The audio output drivers on the ’DAC26 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 330 mW into a bridge terminated 8-Ohm 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.
