Set precise output voltages on up to eight channels simultaneously, making it ideal for multi-channel voltage control, LED dimming, or sensor calibration.\n\nThe DAC7578 is ratiometric — output 0 equals ground and output 4095 equals the reference voltage. By default, Vref is tied to the power pin, but you can cut a jumper to supply an external precision reference for more accurate output control.\n\nKey Features\n\n\n8× 12-Bit DAC Channels – Independent voltage outputs from a single chip with 4096-step resolution\n\nI2C Interface – Simple two-wire control from any microcontroller or SBC\n\n3.3V or 5V Compatible – Works with any logic level\n\nRatiometric Output – 0 to Vref range (Vref tied to power by default, cuttable jumper for external reference)\n\nSTEMMA QT / Qwiic Connectors – Two JST SH connectors for easy I2C daisy-chaining\n\n\nAlso Available\n\n\nDAC6578 Breakout – 8-channel 10-bit version\n\n\nIdeal For\n\nMulti-channel voltage control and waveform generation\nLED brightness control across multiple channels\nSensor calibration and test equipment\nAnalogue signal simulation\n\n\nPackage Contents\n\n1× Adafruit DAC7578 Breakout (assembled)\n\n\n\nNote: STEMMA QT cable not included.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":292,"title":"Default Title","sku":"AF-6223","mpn":"ADA6223","price":47.52,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":10,"option1":"Default Title"}]}
