Product Overview
The TLV320AIC3104 is a Texas Instruments low-power stereo audio codec for Signal_Chain designs requiring integrated stereo record and playback paths. The stereo DAC supports 102 dBA signal-to-noise ratio, 16-, 20-, 24-, or 32-bit data words, and 8 kHz to 96 kHz sample rates. The stereo ADC supports 92 dBA signal-to-noise ratio across the same 8 kHz to 96 kHz sample-rate range.
Analog connectivity includes six audio input pins, configurable as one stereo single-ended pair or one stereo fully differential pair. Output resources include six audio output drivers, stereo fully differential or single-ended headphone drive, and fully differential stereo line outputs. The record path includes programmable microphone bias, automatic gain control, and up to 59.5 dB ADC analog gain for low-level microphone inputs.
System integration is supported through I2C control and audio serial modes including I2S, left-justified, right-justified, DSP, and TDM. Supply ranges include 2.7 V to 3.6 V analog supply, 1.525 V to 1.95 V digital core supply, and 1.1 V to 3.6 V digital I/O supply. The device is supplied in a 32-pin VQFN package measuring 5.00 mm x 5.00 mm.
