With an impressive 112dB signal-to-noise ratio and no MCLK or I2C configuration required, simply pipe I2S data in and get audiophile-grade analogue audio out.\n\nThe PCM5102 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\n112dB SNR / Dynamic Range – Excellent stereo audio output from the PCM5102 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. Pin-compatible with the PCM5100 (100dB SNR) for easy swapping.\n\n\nIdeal For\n\nHigh-fidelity audio output from I2S-capable microcontrollers and SBCs\nWAV and MP3 playback projects demanding clean stereo DAC performance\nAudio prototyping on breadboards with the included header\nDriving powered speakers or amplifier inputs from digital audio sources\n\n\nAlso Consider\n\n\nPCM5100 I2S DAC (100dB SNR) – Pin-compatible, lower-cost alternative\n\n\nPackage Contents\n\n1× PCM5102 I2S Stereo DAC Breakout\n1× Header strip for breadboard use\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":295,"title":"Default Title","sku":"AF-6250","mpn":"ADA6250","price":9.43,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
