## Description

The Adafruit PCM5100 I2S DAC converts digital I2S audio into clean, high-quality stereo line-level output through a 3.5mm jack. With 100dB signal-to-noise ratio and no MCLK or I2C configuration required, simply pipe I2S data in and get great-sounding analogue audio out. The PCM5100 accepts 16, 24, or 32-bit audio and automatically determines the correct format from the WSEL/BCLK ratio. It generates its own master clock internally from the bit clock, so no MCLK connection is needed (though an optional MCLK input is available). Audio output is line-level, centred on ground and not AC-coupled — suitable for amplifiers and powered speakers with 1K ohm or greater input impedance. Key Features 100dB SNR / Dynamic Range – Clean stereo audio output from the PCM5100 chip I2S Input – Just BCLK, WSEL, and DIN (3.3V logic) — no MCLK or I2C configuration needed 16/24/32-bit Audio – Automatically detects bit depth from clock ratio 3.5mm Line-Level Output – Plus breakout pads for direct wiring 3–5V Power – Wide supply voltage range I2S or Left-Justified – Toggle the Format pin to switch modes Configurable Options – Filter mode (normal/low-latency), mute, and 44.1kHz de-emphasis via breakout pads Note: This is a line-level output — it cannot drive headphones directly. Use with amplifiers or powered speakers rated for 1K ohm or greater loads. The PCM5100 is pin-compatible with the higher-spec PCM5102 (112dB SNR). Ideal For Adding high-quality audio output to I2S-capable microcontrollers and SBCs WAV and MP3 playback projects needing clean stereo DAC output Audio prototyping on breadboards with the included header Driving powered speakers or amplifier inputs from digital audio sources Package Contents 1× PCM5100 I2S Stereo DAC Breakout 1× Header strip for breadboard use
