This 16-bit ADC delivers 860 samples per second over I2C, with four single-ended or two differential input channels and a built-in programmable gain amplifier (up to 16×) for boosting small signals.\n\nThe board runs on 2V to 5V power and logic, and includes ferrites for clean analog supply lines. Up to four ADS1115 boards can share a single I2C bus for 16 single-ended inputs. For faster sampling at lower resolution, consider the ADS1015 12-Bit ADC (3,300 samples/second).\n\nKey Features\n\n\n16-Bit Resolution – High-precision measurements at 860 samples per second\n\n4 Channels – Configurable as 4 single-ended or 2 differential inputs\n\nProgrammable Gain Amplifier – Up to 16× gain for small signal measurement\n\n2V to 5V Operation – Compatible with both 3.3V and 5V logic\n\nI2C Interface – Simple two-wire connection with configurable address\n\nConfigurable I2C Address – Up to 4 boards on a single bus (16 inputs total)\n\nClean Analog Supply – Onboard ferrites for quiet AVDD and AGND\n\n\nIdeal For\n\nPrecision sensor measurement and data acquisition\nAdding analog inputs to digital-only microcontrollers\nVoltage and current monitoring\nMulti-channel analog measurement systems\n\n\nPackage Contents\n\n1× ADS1115 16-Bit ADC Breakout Board (assembled and tested)\n1× Header strip\n\n\nResources\n\nAdafruit Learn Guide (Arduino, Raspberry Pi & CircuitPython)\nADS1X15 Arduino Library (GitHub)\nAdafruit Pi Python Library (GitHub)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":6938,"title":"Default Title","sku":"AF-1085","price":31.31,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
