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.\n\nThe 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.\n\nKey Features\n\n\n100dB SNR / Dynamic Range – Clean stereo audio output from the PCM5100 chip\n\nI2S Input – Just BCLK, WSEL, and DIN (3.3V logic) — no MCLK or I2C configuration needed\n\n16/24/32-bit Audio – Automatically detects bit depth from clock ratio\n\n3.5mm Line-Level Output – Plus breakout pads for direct wiring\n\n3–5V Power – Wide supply voltage range\n\nI2S or Left-Justified – Toggle the Format pin to switch modes\n\nConfigurable Options – Filter mode (normal/low-latency), mute, and 44.1kHz de-emphasis via breakout pads\n\n\n\nNote: 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).\n\n\nIdeal For\n\nAdding high-quality audio output to I2S-capable microcontrollers and SBCs\nWAV and MP3 playback projects needing clean stereo DAC output\nAudio prototyping on breadboards with the included header\nDriving powered speakers or amplifier inputs from digital audio sources\n\n\nPackage Contents\n\n1× PCM5100 I2S Stereo DAC Breakout\n1× Header strip for breadboard use\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":296,"title":"Default Title","sku":"AF-6251","mpn":"ADA6251","price":7.52,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
