## Description

Add high-quality amplified I2S digital audio to your project with this TLV320DAC3100 breakout. It provides clean stereo audio for 16Ω headphones and/or mono speaker output for a 4Ω-8Ω speaker, making it handy for compact audio builds without a separate amplifier.The board takes BCLK, WSEL and DIN from an I2S source, then uses I2C for configuration such as gain and output selection. It does not require an MCLK signal, as the built-in PLL can generate MCLK from BCLK, but it does need I2C setup from a microcontroller using Adafruit’s Arduino, CircuitPython or Python library.Power it from 3~5VDC, with 3V suitable for headphone-only use and 5VDC required for speaker support. Logic levels are 3.3V only. The headphone output is AC-coupled, while the speaker output is a class-D amplifier output and should be connected to a speaker only.Extra breakouts include MIC and BIAS for headset microphone detection and headset button sensing, AIN1/AIN2 alternative mix-ins for the audio outputs, and a GPIO pin that can also be used as an IRQ line. Each order includes one DAC breakout and header you can solder on for breadboard use.Specifications:Stereo Audio DAC: with 95-dB SNRSample Rates: Supports 8-kHz to 192-kHz Sample RatesOutputs: Stereo Headphone/Lineout and Mono Class-D Speaker Outputs AvailableMono Class-D BTL Speaker Driver: 2.5 W Into 4-Ω or 1.6 W Into 8-ΩSingle-Ended Inputs: Two Single-Ended Inputs (AIN1/AIN2) With Mixing and Output Level ControlHeadphone Detection: Microphone Bias Headphone DetectionDigital Audio Processing Blocks: 25 Built-in Digital Audio Processing Blocks (PRB_P1 – PRB_P25) Providing Biquad and FIR Filters, DRC, and 3-D StructuresMixing: Digital Mixing CapabilityVolume Control: Pin Control or Register Control for Digital-Playback Volume-Control SettingsSine-Wave Generator: Digital Sine-Wave Generator for Beeps and Key Clicks (PRB_P25)PLL: Programmable PLL for Flexible Clock GenerationAudio Interfaces: I2S, Left-Justified, Right-Justified, DSP, and TDM Audio InterfacesControl Interface: I2C Control With Register Auto-IncrementPower Control: Full Power-Down ControlProduct Dimensions: 33.7mm x 25.4mm x 7.1mm / 1.3" x 1.0" x 0.3"Product Weight: 4.0g / 0.1oz
