(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) If the AIC29 is used to drive high power levels to an 8- load for extended intervals at an ambient temperature above 80°C, multiple vias should be used to electrically and thermally connect the thermal pad on the QFN package to an internal heat dissipating ground plane on the user's PCB.
DescriptionThe TLV320AIC29 is a low-power, high-performance audio codec with 16/20/24/32-bit 95-dB stereo playback, mono record functionality at up to 48 ksps. Two microphone inputs of TLV320AIC29 include independent programmable bias voltages, built-in pre-amps, and hardware automatic gain control, with single-ended or fully-differential signal input capabilities.
The stereo 16- headphone drivers of TLV320AIC29 on the AIC29 support capless as well as ac-coupled output configurations. An 8- BTL differential speaker driver provides up to 400 mW of power and 98-dB SNR, while a differential driver is also available for driving a 32- speaker or telephone earpiece. A programmable digital audio effects processor enables bass treble, midrange, or equalization playback processing. The digital audio data format of TLV320AIC29 is programmable to work with popular audio standard protocols (I2S, DSP, left/right justified) in master or slave mode, and also includes an on-chip programmable PLL for flexible clock generation capability. Highly configurable software power control is provided, enabling 48 ksps stereo audio playback to 16- headphones at 19 mW with a 3.3-V nalog supply level.
The TLV320AIC29 offers a 12-bit measurement ADC and internal reference voltage. It includes an on-chip temperature sensor capable of reading 0.3°C resolution, as well as a battery measurement input capable of reading battery voltages up to 6 V, while operating at an analog supply as low as 3 V. The TLV320AIC29 is available in a 48-lead 7 x 7 mm QFN package.
