TLV320DAC26 (ACTIVE)

Low-Power Stereo DAC with HP/Speaker Amplifier

 

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- 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.
