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.
