Audio Codec Incorporates miniDSP
Offering a sample rate of 192 kHz, Texas Instruments’ TLV320AIC3254 audio codec integrates the miniDSP programmable audio processing engine for running algorithms such as surround sound. The 5 mm² QFN-32-packaged component utilizes PowerTune technology for power consumption from 2.4 mW at 90 dB SNR to 5.1 mW at 100 dB SNR for stereo playback, and from 6 mW at 88 dB SNR to 14.2 mW at 93 dB SNR for stereo recording. The 1.8 V device includes the PurePath drag-and-drop graphical environment, dual integrated LDOs, stereo headphone amplifier, dual microphone programmable gain amplifiers, fractional PLL, and analog input mux. Applications include handsets, portable navigation devices, and portable media devices. The unit complements DM3x, OMAP35x, and OMAP-LI devices. Pricing is $5.45 in 1,000 quantities with a version without miniDSP pricing at $3.45 in 1,000 quantities.
