Overview
The TLV320DAC3100IRHBR is a low-power, highly integrated, high-performance stereo audio Digital-to-Analog Converter (DAC) produced by Texas Instruments. This device features 24-bit stereo playback and includes comprehensive digital audio processing blocks. It integrates headphone drivers and a mono Class-D speaker driver capable of driving loads down to 4 Ω. The TLV320DAC3100IRHBR supports various audio standard protocols such as I2S, left/right-justified, DSP, and TDM modes, and is controlled via the I2C serial bus. The device is available in a 32-pin VQFN package and operates over a temperature range of -40°C to 85°C.
