DESCRIPTION

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-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 provided, enabling stereo audio playback at 48

ksps at 11 mW with a 3.3-V analog supply level.

The ’DAC26 is available in a 32 lead QFN.
