Video: TI Introduces the Lowest Power 1.8-V Audio Codec With Integrated miniDSP in Production Today

Codec boosts audio performance, extends battery life and reduces cost and design complexity for portable device manufacturers

DALLAS, Oct. 27 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a highly integrated audio codec in full production with leading consumer electronics companies to help them meet growing consumer demand for cost-efficient, feature-rich products with better audio quality and longer battery life. The 1.8-V codec combines integrated power management and dual miniDSP audio processing engines to save designers total audio solution cost and make it easier to design advanced audio features in handsets, portable navigation and portable media devices. TI's PurePath(TM) Studio development toolset further eases design complexity and speeds time to market. And the codec's PowerTune(TM) technology increases playback time by allowing designers to tune the device for optimum power use in each operating mode. (See www.ti.com/tlv320aic3254-pr.)

"High-quality sound and feature-rich products are becoming an important consideration in portable product design, which traditionally has implied increased engineering investment to solve complex design issues," said Art George, senior vice president of TI's High-Performance Analog business unit. "TI is addressing these challenges with innovative products like the TLV320AIC3254. Customers are using the TLV320AIC2354 to differentiate their products with advanced audio effects, including multi-band equalization, dynamic bass boost, noise and echo cancellation. At the same time, they're reducing overall cost and complexity to speed their time to revenue."

miniDSP and algorithm library enhance audio performance and ease design complexity

The TLV320AIC3254 is the first product from TI to incorporate the highly programmable miniDSP audio processing engine, which allows users to run complex algorithms on the device while freeing MIPS on the primary processor. Leveraging TI's new codec and its 192-kHz sample rate, customers can add the most comprehensive suite of advanced digital signal processing capabilities to improve audio performance, including 20-band stereo graphic equalizer, multi-band dynamic range compression, custom FIR and IIR filtering, and 3-D processing, without in-house algorithm expertise or increased investment in resources for code development. TI will provide all low-level miniDSP programming. And designers can leverage the PurePath Studio development toolset and TI's library of advanced algorithms to compile, configure and load their application into the integrated miniDSP engines in an intuitive, drag-and-drop graphical environment, simplifying design complexity and reducing time to market.

PowerTune technology reduces power consumption to as little as 2.4 mW

The device also features PowerTune technology to extend battery life without sacrificing audio quality. This technology provides customers with the flexibility to optimize power consumption under any usage model, trading off between ultra low-power operation and signal-to-noise ratio (SNR) for better audio quality. For instance, designers concerned with power consumption can tune their system to consume as little as 2.4 mW in stereo playback when performance is programmed to the 90-dB SNR level. Conversely, customers seeking to maximize performance can achieve 100-dB SNR at 5.1 mW in stereo playback. To further increase performance, the TLV320AIC3254 also provides digital microphone support for improved system-level noise immunity.

Integrated power management simplifies design and reduces cost

The TLV320AIC3254 includes dual integrated LDOs, which provide additional power supply rejection and extend device capability to operate single-supply up to 3.6 V. With integrated stereo headphone amplifier, dual microphone programmable gain amplifiers, fractional PLL and analog input mux, the codec simplifies board design dramatically and reduces final system component count and cost.

Pricing and availability

The TLV320AIC3254 is available today in a space-saving 5 mm x 5 mm QFN-32 package from TI and its authorized distributors. The device is priced at $5.45 in 1000-piece quantities. Advanced audio algorithms are also available today.

In addition, for manufacturers seeking an ultra low-power audio codec without integrated miniDSP functionality, the pin-compatible TLV320AIC3204 is available for $3.45 in 1000-piece quantities. Samples, EVMs and software for both devices are available at www.ti.com/tlv320aic3254.

Extending TI's portfolio of portable audio solutions

The TLV320AIC3254 and TLV320AIC3204 devices are optimized to work with other products from TI's portable audio portfolio, including speaker amplifiers and power management. The codecs can be used in conjunction with TI's DM3x, OMAP35x and OMAP-L1 low-power processors.
