The Texas Instruments (TI) 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.
Art George, senior vice president of TI's High-Performance Analog business unit said customers are using the TLV320AIC2354 to differentiate their products with advanced audio effects, including multi-band equalization, dynamic bass boost, noise and echo cancellation.
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.
The TLV320AIC3254 is available today in a 5x5mm QFN-32 package from TI and its authorized distributors. The device is priced at US$5.45 in 1000-piece quantities. In addition, for manufacturers seeking an ultra low-power audio codec without integrated miniDSP functionality, the pin-compatible TLV320AIC3204 is available for US$3.45 in 1000-piece quantities.
