The TLV320AIC26 is a high-performance, low-power audio codec with
a headphone/speaker amplifier and a 12-bit battery/temperature/
auxiliary measurement SAR ADC. The TLV320DAC26 is a pin- and
software-compatible version of the TLV320AIC26, incorporating a
stereo audio DAC and a headphone/speaker driver and offers the
lowest power playback in TI‘s portfolio.
Key Features
• Stereo DAC and mono audio ADC (’AIC26) support up to 53 kSPS
• 97-dB stereo playback at 11-mW power dissipation
• Audio output drivers provide 325 mW into 8
Ω
and also support
stereo headphones with capless output option
• Integrated PLL for flexible audio clock generation
• Programmable digital audio bass/treble/EQ/de-emphasis
• Microphone preamp and hardware automatic gain control (’AIC26)
• Direct battery measurement accepts up to 6-V input (’AIC26)
