It happens. The SparkFun Qwiic 12 Bit ADC can provide four channels of I\u003csup\u003e2\u003c\/sup\u003eC controlled ADC input to your Qwiic enabled project. These channels can be used as single-ended inputs, or in pairs for differential inputs. What makes this even more powerful is that it has a programmable gain amplifier that lets you \"zoom in\" on a very small change in the analogue voltage (but will still affect your input range and resolution). Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1\"-spaced pins in case you prefer to use a breadboard.\u003c\/p\u003e\n\u003cp\u003eThe ADS1015 uses its own internal voltage reference for measurements, but a ground and 3.3V reference are also available on the pinouts for users. This ADC board includes screw pin terminals on the four channels of input, allowing for solderless connection to voltage sources in your setup. It also has an address jumper that lets you choose one of four unique addresses (0x48, 0x49, 0x4A, 0x4B). With this, you can connect up to four of these on the same I\u003csup\u003e2\u003c\/sup\u003eC bus and have sixteen channels of ADC. The maximum resolution of the converter is 12-bits in differential mode and 11-bits for single-ended inputs. Step sizes range from 125μV per count to 3mV per count depending on the full-scale range (FSR) setting.\u003c\/p\u003e\n\u003cp\u003eWe have included an onboard 10K trimpot connected to channel A3. This is handy for initial setup testing and can be used as a simple variable input to your project. But don't worry, we added an isolation jumper so you can use channel A3 however you'd like.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e The I\u003csup\u003e2\u003c\/sup\u003eC address of the ADS1015 is 0x48 and is jumper selectable to 0x49, 0x4A, 0x4B. A multiplexer\/Mux is required to communicate to multiple ADS1015 sensors on a single bus. If you need to use more than one ADS1015 sensor consider using the Qwiic Mux Breakout.\u003c\/p\u003e\n\u003cp\u003eGet Started with the Sparkfun Qwiic 12-Bit ADC Hookup guide\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eADS1015\n\u003cul\u003e\n\u003cli\u003eOperating Voltage (V\u003csub\u003eDD\u003c\/sub\u003e): 2.0V-5.5V\n\u003cul\u003e\n\u003cli\u003e(Note: When powering with a Qwiic cable, the input range is only 3.3v)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -40°C to 125°C\u003c\/li\u003e\n\u003cli\u003eOperation Modes: Single-Shot, Continuous-Conversion (Default), and Duty Cycling\u003c\/li\u003e\n\u003cli\u003eAnalog Inputs:\n\u003cul\u003e\n\u003cli\u003eMeasurement Type: Single-Ended (Default)\u003c\/li\u003e\n\u003cli\u003eInput Voltage Range: GND to V\u003csub\u003eDD\u003c\/sub\u003e\n\u003c\/li\u003e\n\u003cli\u003eFull Scale Range (FSR): ±.256V to ±6.114V (Default: 2.048V)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eResolution:\n\u003cul\u003e\n\u003cli\u003e12-bit (Differential) or 11-bit (Single-Ended)\u003c\/li\u003e\n\u003cli\u003eLSB size: 0.125mV - 3mV (Default: 1 mV)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eSample Rate: 128 Hz to 3.3 kHz (Default: 1600SPS)\u003c\/li\u003e\n\u003cli\u003eCurrent Consumption (Typical): 150μA-200μA\u003c\/li\u003e\n\u003cli\u003eI\u003csup\u003e2\u003c\/sup\u003eC Address: 0x48 (Default), 0x49, 0x4A, or 0x4B\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eScrew pin terminals for solderless connection to voltage sources\u003c\/li\u003e\n\u003cli\u003eFour unique I\u003csup\u003e2\u003c\/sup\u003eC addresses:\n\u003cul\u003e\n\u003cli\u003e0x48\u003c\/li\u003e\n\u003cli\u003e0x49\u003c\/li\u003e\n\u003cli\u003e0x4A\u003c\/li\u003e\n\u003cli\u003e0x4B\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e2x Qwiic connection ports\u003c\/li\u003e\n\u003cli\u003eOnboard 10K trimpot\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSchematic\u003c\/li\u003e\n\u003cli\u003eEagle Files\u003c\/li\u003e\n\u003cli\u003eHookup Guide\u003c\/li\u003e\n\u003cli\u003eADS1015 Datasheet\u003c\/li\u003e\n\u003cli\u003eArduino Library\u003c\/li\u003e\n\u003cli\u003eGitHub Product Repo\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":48624135831770,"sku":"tus1789684164958","price":14.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/sparkfun-qwiic-12-bit-adc---4-channel-ads1015_1.jpg?v=1789684170","url":"https:\/\/memoryfoamwear.shop\/products\/sparkfun-qwiic-12-bit-adc-4-channel-ads1015","provider":"My Store","version":"1.0","type":"link"}
