Simplify portable device designs and reduce cost using TI's new low-power audio codec with integrated Class-D amplifier
A new stereo audio codec from TI enables CD quality playback and extends battery life in portables 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 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 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.
