Texas Instruments High-Performance Analog CODECS TLV320AIC33IGVX

The TLV320AIC33IGVX is a low power stereo audio codec designed for portable audio and telephony applications. It features a compact 7x7mm 48-QFN package and supports a variety of audio input and output configurations, including single-ended and fully differential setups. The codec provides stereo 48-kHz DAC playback with a power consumption as low as 14 mW from a 3.3-V analog supply, making it suitable for battery-operated devices. The device includes an integrated microphone bias, a digitally controlled stereo microphone preamplifier, and automatic gain control (AGC). It supports sampling rates from 8 kHz to 96 kHz for both the audio DAC and ADC, with signal-to-noise ratios of 100 dBA and 92 dBA, respectively. The playback path features programmable volume controls and mix/mux capabilities, while the output drivers can drive various load configurations, including stereo headphones and speakers. The TLV320AIC33IGVX supports multiple digital audio data formats, including I¬=S, left/right-justified, DSP, and TDM modes, and offers a programmable PLL for flexible clock generation. It operates with a range of power supply voltages, making it versatile for different applications. This codec is ideal for engineers looking for a compact, efficient audio solution for their projects.
