Designed for microcontrollers lacking analog inputs, it supports a wide voltage range (2.0V-5.5V) and communicates via I2C, making it ideal for Arduino and Raspberry Pi projects requiring accurate analog signal measurement with flexible sampling rates and power-efficient operation. ## Description Description: For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data.

But I was wrong. It appears the glitch was in the ADC code and not the hardware. If your ADC does not behave like a 16-bit ADC, experiment with the code settings. Review: Perfect simple ADC for Arduino/Raspberry PI projects - Great little device. Simple I2C interface. Configure and Read. Includes multiple gain ranges (+/-6v to +/-250mV) from a single supply. Yes it measures below ground with a single supply. The differential measurement capability is amazing (measuring current through a resistor in both directions). Used this device to measure shunt currents on a solar battery system (0.000750 ohm resistor). Connected to a Raspberry PI Zero for I2C communication and Wifi connectivity. Amazingly accurate. The different sampling rates offer 'effective' filtering for noisy signals and the fast sampling is great for higher speed signals. ## Features - High precision ADS1115 16 Bit 4 Channel Analog-to-Digital ADC Converter - An easy to use I2C ADC Converter, with Programmable Gain Amplifier - Especially a good tool for Raspberry Pi that doesn't come with analog GPIO pins - Wide voltage supply range: 2.0V to 5.5V, operate in a comparator mode which is helpful for maintaining accuracy - Single-Shot Mode: Auto Shut Down; Programmable data rate: 8sps-860sps ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #43,919 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #52 in Signal Converters | | Customer Reviews | 4.2 out of 5 stars 166 Reviews | ## Images ![HiLetgo 3pcs ADS1115 16 Bit 16 Byte 4 Channel I2C IIC Analog-to-Digital ADC PGA Converter with Programmable Gain Amplifier High Precision ADC Converter Development Board for Arduino Raspberry Pi - Image 1](https://m.media-amazon.com/images/I/61hNh0biz0L.jpg) ## Questions & Answers **Q: how to use 2 boards to get 8 channels? are the I2C addresses configurable?** A: Yes, these boards are addressable. You short ADDR pin to Vcc, or GND or SDA or SCL to program board address. You can use maximum 4 of these boards, total 16 single ended channels or 8 differential. See 5th image on Amazon page for these boards or go to Adafruit website for more details. BTW be aware of knock off ICs. Many boards I worked with were advertised and sold as 16 bit but actual board worked as 12-bit only. So if you work with these and have problems getting 16-bit resolution...you have been forewarned :). Good luck. **Q: Can this read differential voltages higher than the input voltage? I want to read cell voltages in a 48v battery pack** A: If you use a voltage divider with two resistors you can. Search google voltage divider. But you lose a little bit accuracy. There are good videos on YouTube about this ADS1115 explain all that. **Q: Could I use this to read voltages from 0 to 100 mV from a sensor?** A: Yes, you can read voltages from 0 to 5V. Be careful not to apply more than 5V or you will destroy the IC. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Updated Review *by S***H on October 26, 2021* This ADC initially behaved like a 12-bit ADC, and I gave it a bad review.

Bought and tested three using an Arduino and they work perfectly with the ADS1115 Arduino library from wollewald/ADS1115_WE. The library has a sketch to identify the chips correctly and it identified all three boards as having true ADS1115 and it tested for and saw all 16 bits of sampling correctly. For the price and convenience, cant beat these. Came with a header to solder onto to use on a breadboard. BTW, much cheaper than the digikey versions. ## Frequently Bought Together - HiLetgo 3pcs ADS1115 16 Bit 16 Byte 4 Channel I2C IIC Analog-to-Digital ADC PGA Converter with Programmable Gain Amplifier High Precision ADC Converter Development Board for Arduino Raspberry Pi - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - Raspberry Pi Camera Module V2-8 Megapixel,1080p (RPI-CAM-V2) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/152293523-hiletgo-3pcs-ads1115-16-bit-16-byte-4-channel-i2c](https://www.desertcart.tn/products/152293523-hiletgo-3pcs-ads1115-16-bit-16-byte-4-channel-i2c) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-07*
