Dec 29, 2008

DALLAS (Dec. 29, 2008) - A new low-power stereo audio codec from Texas Instruments Incorporated (TI) (NYSE: TXN) enables CD quality playback and extends battery life in portable products such as cell phones, portable navigation devices and portable media players. The TLV320AIC3107 codec integrates a stereo headphone amplifier and mono Class-D speaker amplifier to substantially reduce board area and cost by 20 percent when compared to discrete solutions (See www.ti.com/tlv320aic3107-pr.)

Key Features

  • Stereo 8-96 ksps DAC with 97 dB signal-to-noise ratio (SNR) and 8-96 ksps ADC with 92 dB SNR
  • Low power consumption of 15 mW at 48 kHz with a 3.3-V analog supply
  • Integrated mono Class-D speaker amplifier capable of driving 1 W into 8-Ohm load
  • Low impedance passive analog switch
  • Integrated phase-locked loop (PLL)
  • Multiple inputs and outputs programmable in single-ended or fully differential configurations

Key Benefits

  • SNR performance enables CD quality playback
  • Extends playback time
  • Highly-efficient amplifier prolongs battery life and saves board space
  • Bypasses codec for low-power mode
  • Allows for simplified clocking scheme and lowers system cost
  • Maximizes design flexibility

Availability and pricing

The TLV320AIC3107 is available today in a space-saving 5 mm x 5 mm QFN-40 package from TI and its authorized distributors. The device is priced at $3.85 in 1000-piece quantities. A 3.5mm x 3mm WCSP package will be available in 1Q2009.
