Product Overview
The TLV320AIC3110 is a Texas Instruments low-power audio codec for Signal_Chain designs requiring integrated playback, record, processing, and output drive functions. Playback uses stereo DAC channels with 95 dB SNR, while record functionality uses a mono ADC with 91 dB SNR. Separate DAC and ADC sample rates are supported from 8 kHz to 192 kHz, with 16-, 20-, 24-, and 32-bit digital audio interface resolution.
The digital audio interface supports I2S, left-justified, right-justified, DSP, and TDM operation in master or slave configurations. Register control is through an I2C interface with auto-increment. The analog front end includes one differential and three single-ended microphone inputs, selectable MICBIAS at 2 V, 2.5 V, or AVDD, and an ADC PGA gain range from 0 dB to 59.5 dB.
For output stages, the device includes stereo differential Class-D speaker amplification rated at 1.29 W for an 8-ohm BTL speaker driver, plus headphone attenuation and gain controls. It is supplied in a 32-pin VQFN (RHB), 5.00 mm x 5.00 mm package and operates across specified analog, digital core, digital I/O, and Class-D supply ranges.
