Overview
The TLV320AIC3120IRHBT, produced by Texas Instruments, is a highly integrated, low-power mono audio codec designed for high-performance audio applications. This device features a mono audio DAC with a 95-dB signal-to-noise ratio (SNR) and a mono audio ADC with a 90-dB SNR. It supports sample rates ranging from 8 kHz to 192 kHz for both DAC and ADC. The TLV320AIC3120IRHBT also includes an instruction-programmable embedded miniDSP, enabling advanced digital audio processing capabilities such as bass boost, treble, and equalization (EQ) with up to five biquads for record and six biquads for playback.
The device integrates several analog features, including a microphone interface with bias, preamp PGA, and automatic gain control (AGC), as well as headphone and line driver outputs. It also features a mono Class-D speaker driver capable of delivering up to 2.5 W into a 4 Ω load or 1.6 W into an 8 Ω load. The TLV320AIC3120IRHBT is controlled via an I2C serial bus and supports various audio interface protocols such as I2S, left-justified, right-justified, DSP, and TDM.
